American Airpower Strategy in Korea, 1950-1953

Online Description

The Korean War was the first armed engagement for the newly formed U.S. Air Force, but far from the type of conflict it expected or wanted to fight. As the first air war of the nuclear age, it posed a major challenge to the service to define and successfully carry out its mission by stretching the constraints of limited war while avoiding the excesses of total war. Conrad Crane analyzes both the successes and failures of the air force in Korea, offering a balanced treatment of how the air war in Korea actually unfolded. He examines the Air Force’s contention that it could play a decisive role in a non-nuclear regional war but shows that the fledgling service was held to unrealistically high expectations based on airpower’s performance in World War II, despite being constrained by the limited nature of the Korean conflict. Crane exposes the tensions and rivalries between services, showing that emphasis on strategic bombing came at the expense of air support for ground troops, and he tells how interactions between army and air force generals shaped the air force’s mission and strategy. He also addresses misunderstandings about plans to use nuclear, biological, and chemical weapons in the war and includes new information from pilot correspondence about the informal policy of “hot pursuit” over the Yalu that existed at the end of the war. The book considers not only the actual air effort in Korea but also its ramifications. The air force doubled in size during the war and used that growth to secure its position in the defense establishment, but it wagered its future on its ability to deliver nuclear weapons in a high-intensity conflict—a position that left it unprepared to fight the next limited war in Vietnam. As America observes the fiftieth anniversary of its initial engagement in Korea, Crane’s book is an important reminder of the lessons learned there. And as airpower continues to be a cornerstone of American defense, this examination of its uses in Korea provides new insights about the air force’s capabilities and limitations.


🔫 Author Background

Conrad C. Crane is a U.S. military historian affiliated with the U.S. Military Academy at West Point (noted in the book’s front matter disclaimer). He previously authored Bombs, Cities, and Civilians: American Airpower Strategy in World War II (Kansas, 1993), a study of strategic bombing doctrine and practice that informs this Korea volume. Crane frames the Korean case as the problem of wielding a powerful air arm under strict limits—what he elsewhere calls the “frustrations of limited war.”


🔍 Author’s Main Issue / Thesis

Crane argues that U.N./U.S. airpower in Korea was essential but bounded: political, geographic, intelligence, and technological limits forced strategists to substitute coercive “air pressure” for decisive strategic attack, while CAS, interdiction, and air superiority prevented defeat and shaped negotiations rather than delivering capitulation. He contends target selection and campaign design were repeatedly re‑written by coalition diplomacy, sanctuary rules, and escalation fears; when expectations of quick strategic effect failed, airmen adapted with interdiction, night operations, and selective “demonstration” strikes (e.g., Suiho). The broader lesson is that airpower’s military and political utility must be weighed against diplomatic repercussions and world opinion in limited wars.


🧭 One‑Paragraph Overview

From prewar doctrine through armistice, Crane traces how FEAF and Washington re‑scoped airpower’s role several times: initial air supremacy and a strategic attack plan gave way to interdiction and CAS under Chinese pressure; then to a coercive “air pressure” approach synchronized with armistice talks; and finally to precision‑seeking but constrained bombardment featuring SHORAN‑guided night B‑29s and expanded fighter‑bomber duties. The book foregrounds limits—sanctuaries in Manchuria/USSR, coalition politics, ROE, weather/terrain, and technology/accuracy—and shows adaptation: GHQ/FEAF target committees, night operations, guided munitions (Razon/Tarzon), leaflets/psywar, and dam/powerplant attacks designed to raise costs without triggering general war. Strategic effect was cumulative and conditional rather than decisive; the Air Force kept the front stable, attrited the enemy, and contributed to the armistice while learning hard lessons about coercion, accuracy, and joint integration.


🎯 Course Themes Tracker

  • Limits on airpower — Sanctuary, alliance diplomacy, ROE, accuracy, weather/terrain, adversary adaptation.

  • Expectations vs. reality — Early strategic‑attack optimism → attritional interdiction/CAS → calibrated “air pressure.”

  • Adaptation & learning — Night SHORAN; guided munitions; target committees; dam/power campaigns; psywar integration.

  • Efficacy — Tactical/operational success (air superiority, CAS, interdiction) > strategic coercion; political effect mediated by talks.

  • Alliance dynamics — U.S.–UK friction over warnings/urban strikes; Navy/Marine–USAF control debates; joint target boards.

  • Domain interplay — Air–naval coordination (TF‑77), radar/ISR/C2 (AN/MPQ‑2; SHORAN), EW, and psywar.


🔑 Top Takeaways

  • Airpower mattered enormously—but within tight political and geographic bounds, it coerced at the margins rather than deciding the war outright.

  • Expectations reset: MacArthur’s promise that air could isolate and destroy the enemy gave way to his own admission that “perhaps too much was expected of the air.” (p. 54).

  • Accuracy constraints shaped strategy: SHORAN improved night CEPs yet produced predictable approach paths that MiG/searchlight networks exploited; daytime B‑29s were driven to nights. (pp. 139–140, 154).

  • Coercive “air pressure” integrated mass raids, powerplant/dam strikes, and psywar to influence negotiations without provoking general war. (pp. 118–123, 163).

  • MoE divergence: tonnage/sorties and bridge counts masked limited strategic payoff; only 4% of fighter‑bomber bombs hit pinpoint targets in 1953. (p. 151).

  • Joint politics matter: target approval and public messaging were as decisive as bombs, reflecting coalition sensitivities and escalation risk. (pp. 42–43, 123–125).


📒 Sections

Preface

Summary: Crane positions the study as a companion to his WWII work, shifting from the “temptations of total war” to the “frustrations of limited war.” He signals a central concern: how to select targets and design campaigns that create political leverage without diplomatic blowback. He also notes the continuity in debates over precision, morality, and publicity in strategic bombing from WWII into Korea. The preface foreshadows his judgment that Korea’s air strategy is most instructive when viewed through limits and adaptation.

Key Points:

  • Korean airpower must be read through the lens of limited war.

  • Public perception and diplomatic costs constrain military choices.

  • Korea offers cumulative lessons on coercion and precision begun in WWII.

Cross‑Cutting Themes: Limits; expectations vs. reality; coercion politics.

Limits Map (mini): Political—coalition optics, world opinion; Legal—warnings/ROE; Strategic—avoid general war; Intelligence—closed society; all mostly exogenous, partially relaxable by messaging and target discrimination.


Introduction

Summary: Crane frames Korea as a test of a new service’s doctrine under real constraints—sanctuary, alliance, and nuclear thresholds. He contrasts early hopes for decisive strategic bombing with the messy realities of interdiction and CAS within a coalition, arguing airpower’s political utility must be balanced against its diplomatic repercussions. He emphasizes that what military leaders deem “humane” (e.g., warnings) may read differently to diplomats and foreign press. He closes that the 1950–53 air strategy, forged by political, military, and resource constraints, remains relevant for contemporary limited wars.

Key Points:

  • Airpower’s flexibility tempts over‑promise; limits bound outcomes.

  • Publicity, leaflets, warnings became strategic variables.

  • Coercion without escalation is the core design problem.

Cross‑Cutting Themes: Expectations vs. reality; legitimacy; coercion.

Limits Map (mini): Political (UN legitimacy, UK/Asian opinion), Strategic (sanctuaries), Legal (IHL/ROE), Info (propaganda battles). Largely exogenous, partially relaxable via messaging and target choice.


Chapter 1: Precedents and Preconceptions

Summary: Crane surveys WWII precedents (area incendiaries; “precision” in relative terms) and postwar doctrine, noting the USAF’s delay in publishing a core doctrine manual until 1953. He shows how SAC primacy and atomic thinking coexisted uneasily with the very conventional problem in Korea. Interservice debates (e.g., Ofstie vs. Anderson) foreshadowed control/friction over CAS and targeting in Korea. Leaflet/psywar practices from WWII informed Korea’s later mass warning campaigns. Overall, preconceptions primed early strategic‑attack optimism that met Korea’s political and geographic realities badly.

Key Points:

  • WWII “precision” remained relative; incendiary campaigns shaped imagination.

  • Postwar USAF doctrine lag; SAC overshadowed tactical concerns.

  • Early Korea planning reused WWII psywar/warning patterns.

  • Interservice CAS control and publicity debates were pre‑loaded.

Cross‑Cutting Themes: Institutional path dependence; doctrine‑practice gaps.

Limits Map (mini): Strategic (nuclear thresholds); Organizational (doctrine lag, SAC focus); Political (coalition sensitivities). Endogenous and exogenous; partly relaxable via theater‑level adaptations.


Chapter 2: Opening Moves

Summary: After 25 June 1950, FEAF rapidly achieved air supremacy over the NKAF, but basing, logistics, and night interdiction proved hard. Weyland pushed Stratemeyer to formalize targeting and curb ad hoc tasking; the GHQ Target Committee created order, shifting B‑29s off close support to interdiction/strategic targets. B‑26 night intruders improvised tactics amid poor maps/ordnance and mountainous terrain—an early warning about accuracy and survivability. Diplomatically, warnings and tonnage‑based press releases triggered British and State Department concerns about mass bombing optics.

Key Points:

  • Target committees professionalized air tasking. (p. 34).

  • Night interdiction was risky; old munitions and terrain limited effects. (p. 42).

  • Early publicity on tonnage drew diplomatic pushback. (pp. 42–43).

  • B‑29s refocused to interdiction/strategic targets from 4 Aug 1950. (p. 34).

Cross‑Cutting Themes: Institutions vs. improvisation; legitimacy management.

Limits Map (mini): Political (UK/State optics), Operational (basing, terrain), Tech (night accuracy), Info (press narratives). Mixed origins; modestly relaxable via process, messaging, and kit.


Chapter 3: Airpower Gets Its Chance

Summary: With Pusan stabilized and reinforcements arriving, FEAF prosecuted a strategic plan against NK industry and transportation. MacArthur declared airpower could deny Yalu‑borne reinforcements, only to concede later that “perhaps too much was expected of the air.” (p. 54). FEAF destroyed much of North Korea’s limited industrial base, but sanctuary and external sustainment blunted decisive effects. As Chinese intervention changed the war, the strategic campaign collided with MiG‑15s and flak, forcing adaptations and foreshadowing the night SHORAN turn.

Key Points:

  • Early strategic targeting achieved high physical damage. (p. 42).

  • Expectation reset captured in MacArthur’s own words. (p. 54).

  • Sanctuary/external supply limited strategic leverage.

  • MiG threat and defenses began to constrain daylight B‑29 ops.

Cross‑Cutting Themes: Expectations vs. reality; sanctuary; adaptation.

Limits Map (mini): Strategic (Manchurian/USSR sanctuary), Operational (MiG threat), Intelligence (closed target system), Tech (escort/ECM gaps). Mixed; some relaxed by night/SHORAN/EW shifts.


Chapter 4: Choosing New Targets and Restoring the Balance

Summary: During UN withdrawal/winter 1950–51, Bomber Command moved mainly to interdiction; maximum‑effort incendiary raids burned large portions of Pyongyang (3 & 5 Jan 1951) but winter conditions limited fires. (pp. 63–64). FEAF and Navy pressed rail and marshaling yards to slow the enemy, while domestic/international optics remained volatile. USAF’s own assessments warned that “specialized employment of medium bombers in the strategic role is a luxury we cannot afford.” (p. 63).

Key Points:

  • Interdiction became Bomber Command’s main mission. (p. 63).

  • Jan 1951 incendiary raids: spectacular but weather‑bounded. (pp. 63–64).

  • Internal critique: strategic medium bomber usage low payoff. (p. 63).

  • Press messaging and warnings remained fraught.

Cross‑Cutting Themes: Means–ends fit; measuring effect vs. damage.

Limits Map (mini): Operational (weather/terrain), Resource (sortie allocation), Political (press optics), Adversary (dispersal). Mostly exogenous; work‑arounds via mission mix and messaging.


Chapter 5: Talking and Dying

Summary: With armistice talks opening in July 1951, Ridgway sought to maintain pressure primarily by air, authorizing large punitive raids timed to negotiation rhythms. (pp. 76–77). LeMay decried concern about SAC’s ability after costly B‑29 episodes, while Nam Il accused UN forces of “indiscriminate… bombing.” (p. 90). FEAF’s campaign increasingly balanced operational punishment against diplomatic signaling, experimenting with leaflets/warnings and city strikes designed to influence enemy calculus without uncontrolled escalation.

Key Points:

  • Ridgway: “unrelenting pressure” concept; large city raids synchronized with talks. (pp. 76–77).

  • Competing narratives: enemy atrocity claims vs. UN restraint/warnings. (p. 90).

  • Air as primary coercive instrument under stabilized lines.

Cross‑Cutting Themes: Coercion/compellence; propaganda contest.

Limits Map (mini): Political (armistice optics), Legal (warnings, ROE), Strategic (no escalation), Info (propaganda). Exogenous; managed via target timing and psywar.


Chapter 6: Manning and Inspiring the Force

Summary: Crane dives into human factors—reservist integration, “fear of flying,” crew rotation, and morale. LeMay enforced strict standards to “nip… in the bud” motivation problems and resisted changes that would accelerate burnout of medium bomber crews. (pp. 105–107). As B‑29s shifted to night, risk patterns changed; fighter‑bomber pilots bore severe stress under low‑level flak and rugged terrain. Public culture (e.g., Hollywood’s Strategic Air Command) became a narrative tool to valorize service and sustain retention. (pp. 109–110).

Key Points:

  • Rotation policy and abort scrutiny as performance levers. (pp. 105–107).

  • Fighter‑bomber stress > ace narratives; survivability as a core MoE. (p. 107).

  • Culture/film used to shore up morale. (pp. 109–110).

Cross‑Cutting Themes: Human capital; measuring effectiveness via survivability and persistence.

Limits Map (mini): Resource/Time (crew pipelines), Organizational (rotation/standards), Tech (aircraft survivability). Endogenous; adjusted via policy and training.


Chapter 7: Applying Air Pressure

Summary: Under Clark/Weyland/Smart, FEAF formalized an “Air Attack Program” prioritizing air superiority, then “maximum selected destruction,” then ground support; the target list emphasized aircraft, airfields, electric power, and transportation nodes. (p. 118). Ridgway initially balked at powerplant attacks; by June 1952, JCS loosened restrictions, enabling the Suiho hydroelectric strike on 23 June—a joint, synchronized raid intended to raise costs without escalation. (pp. 119–133). Mass raids like PRESSURE PUMP (11 Jul) paired with leaflets/warnings to demonstrate UN capability and shape talks. (pp. 123–125).

Key Points:

  • Formal target priorities re‑centered coercive aims. (p. 118).

  • Suiho raid as interservice showcase and coercive signal. (pp. 119–133).

  • Psywar: STRIKE/BLAST leaflets and tailored warnings. (pp. 123–125).

  • State/press sensitivities required carefully managed messaging. (pp. 124–125).

Cross‑Cutting Themes: Strategy–policy alignment; coercive communication; joint integration.

Limits Map (mini): Political (sanctuary, allied optics), Strategic (no general war), Intelligence (target utility), Tech (night accuracy). Exo/endo; addressed via joint planning, psywar, and selective target sets.


Chapter 8: The Quest for Better Bombs and Bombing

Summary: Seeking effect under constraints, FEAF/SAC pursued guided bombs (Razon/Tarzon) and radar aids (AN/MPQ‑2, SHORAN). Razon had mixed results; Tarzon was dangerous to employ and suspended after accidents. (pp. 132–134). SHORAN delivered strong CEPs but created predictable approach paths exploited by searchlight‑MiG networks; 10 June 1952 night defenses downed two B‑29s, driving further ECM and night‑fighting adaptations. (pp. 139–140, 154). Fighter‑bomber accuracy declined with higher‑altitude tactics; by early 1953, only 4% of bombs hit pinpoint targets and carriers rediscovered that “the Korean war is ultimately a dive‑bombing campaign.” (pp. 150–151).

Key Points:

  • Razon/Tarzon: costly complexity; limited payoff under combat conditions. (pp. 133–134).

  • SHORAN: accurate but tactically constraining; triggered enemy adaptation. (pp. 139–140, 154).

  • AN/MPQ‑2 blind bombing CEP ≈ 1,300 ft—uneconomical for B‑29 CAS. (p. 138).

  • Accuracy crisis: 4% pinpoint hits; Navy orders dive‑bombing revival. (pp. 150–151).

Cross‑Cutting Themes: Tech limits; enemy adaptation; MoE realism.

Limits Map (mini): Tech (guidance reliability, CEP), Operational (enemy IADS), Resource (training/maintenance), Adversary (searchlight/MiG). Mixed; addressed via ECM, tactics, training.


Chapter 9: The Final Acts

Summary: Clark endorsed maximum air pressure within acceptable cost, as ground stalemate persisted and nuclear/CW/BW options were examined but not used. (p. 169). FEAF expanded dam attacks and introduced F‑86F fighter‑bombers for CAS (Feb 1953), with survivability prized over raw accuracy. (p. 163). USAF–Navy joint processes improved in 1953 even as institutions in Washington argued budgetary cost‑effectiveness using Korea sortie/tonnage data. (p. 163). The war closed with an armistice shaped partly by cumulative aerial punishment and the perceived ability to increase it further—coercion by credible prospect, not annihilation.

Key Points:

  • Air pressure seen as the only scalable coercive lever absent ground offensives. (p. 169).

  • F‑86 CAS: survivability‑driven tradeoffs. (p. 163).

  • Dam campaign and selective visibility. (pp. 163–164).

  • Joint cooperation up; institutional rivalry persists. (p. 163).

Cross‑Cutting Themes: Coercive credibility; survivability as MoE; joint politics.

Limits Map (mini): Strategic (no nukes, sanctuary), Legal/Normative (dam optics), Operational (IADS), Resource (crew/airframe fatigue). Largely exogenous; adapted via selective targeting, messaging, and force mix.


Chapter 10: Legacies and Conclusions

Summary: Crane concludes Korea demonstrates how hard it is to pick air targets that produce desired political effects under tight constraints; military utility must always be balanced against diplomatic repercussions and world opinion. (p. 184). He judges airpower in Korea effective but not decisive: air superiority, CAS, and interdiction were indispensable to survival and bargaining leverage, yet sanctuary and supply from abroad prevented decisive strategic collapse. The cumulative “air pressure” approach worked as bounded coercion, not as standalone victory. He urges contemporary strategists to internalize limits, align MoE with political aims, and design campaigns that integrate messaging, joint tools, and accurate assessments of enemy adaptation.

Key Points:

  • Target selection for political effect is the core difficulty in limited wars. (p. 184).

  • Effective ≠ decisive; sanctuary and external supply matter.

  • MoE must be tied to political objectives and enemy adaptation.

  • Korea’s air strategy remains a live template for limited war design.

Cross‑Cutting Themes: Ends–ways–means alignment; coercion design; learning.

Limits Map (mini): Political/Strategic primacy; Info/legitimacy; Adversary adaptation. Mostly exogenous; mitigated, not solved.


🧱 Limits Typology (case‑specific)

  • Political: UN legitimacy; allied opinion (UK protests re warnings/“mass bombing”); escalation risk with China/USSR; sanctuary rules. Source: exogenous; adjustability: partial via messaging/targeting; effect: strategic; adaptations: leaflets, selective visibility, joint target boards; outcome: sustained coercion without escalation.

  • Legal/Normative: ROE on cities/dams/powerplants; warnings/leaflets; IHL sensitivities. Source: exogenous; adjustability: limited; effect: strategic/operational; adaptations: STRIKE/BLAST warnings; controlled narratives; outcome: mixed reputational effects.

  • Strategic: War aims short of regime change; no strikes into Manchuria/USSR; nuclear/CW/BW off the table. Source: exogenous; adjustability: low; effect: strategic; adaptations: “air pressure” in lieu of decisive attack; outcome: armistice, not surrender.

  • Operational: Weather/terrain; basing/logistics; joint C2; night ops; MiG/searchlights/IADS. Source: mixed; adjustability: moderate; effect: operational; adaptations: night SHORAN, ECM, escort, dive‑bombing revival; outcome: survivable but accuracy‑bounded effects.

  • Technological/Capability: CEP limits; guided bomb reliability; radar aid errors; survivability of medium bombers vs jets. Source: endogenous; adjustability: moderate; effect: tactical/operational; adaptations: Razon/Tarzon trials; MPQ‑2; SHORAN; ECM; outcome: incremental gains, new vulnerabilities.

  • Intelligence/Information: Closed NK system; poor maps/photos; propaganda battles. Source: exogenous; adjustability: partial; effect: operational/strategic; adaptations: recon, psywar, measured publicity; outcome: targeting friction; mixed IO effects.

  • Adversary Adaptation: Dispersal; camouflage/deception; night movement; IADS concentration on SHORAN arcs. Source: exogenous; adjustability: low; effect: operational; adaptations: ECM, approach variation, night tactics; outcome: attritional duel. (p. 154).

  • Resource/Time: Sortie generation, crew pipelines, airframe wear. Source: endogenous; adjustability: moderate; effect: operational; adaptations: rotation policies, training, prioritization; outcome: sustained but not surging pressure.


📏 Measures of Effectiveness (MoE)

  • What they tracked then: sorties/tonnage; bridges/rail cuts; city block damage; air‑to‑air tallies; CEP estimates; survivability (loss/abort rates); leaflet counts.

  • Better MoE today (with rationale):

    • Strategic: Negotiation milestones linked to specific aerial actions; enemy logistic throughput decay (not just bridges destroyed); cost‑imposition indices combining repair time, reroute distance, and breakdowns; perception measures (elite/foreign press content analysis).

    • Operational: Sustainment lag at the FEBA; repeatable traffic‑flow metrics; enemy sortie suppression windows; coercive signal fidelity (timing, visibility).

    • Tactical: CEP against mission‑relevant target sets; platform survivability per effect; night interdiction kill assessment with sensor corroboration.

  • Evidence summary: Fighter‑bomber CEP degraded with altitude changes; by early 1953, <50% within 500 ft; 4% pinpoint hits—underscoring the gap between sortie counts and useful effect. (p. 151). SHORAN improved B‑29 CEP (<600 ft in visual conditions) but prompted predictable routes exploited by enemy night defenses. (pp. 139–140, 154). MPQ‑2 blind CAS CEP ≈ 1,300 ft—cost‑inefficient. (p. 138).

📖 Historiographical Context

Engages USAF official history (Futrell), Navy accounts (Hallion), and OR studies (JHU ORO; RAND) to triangulate effects and perceptions; revisits WWII precision debates to stress “precision in a relative sense.” (pp. 138–141). Challenges narratives that airpower alone could compel capitulation, instead highlighting coalition politics, sanctuary, and targeting friction; nuances Marine–USAF CAS performance comparisons via Barcus Report and ORO data. (pp. 63–64).


🧩 Frameworks & Methods

  • Levels: Strategic (coercion/armistice leverage), Operational (interdiction/city raids), Tactical (CAS, SEAD, A2A).

  • Instruments: Air superiority; interdiction; strategic attack (powerplants/dams); CAS; psywar/leaflets; radar aids (AN/MPQ‑2); SHORAN; ECM; guided munitions (Razon/Tarzon). (pp. 118, 132–140).

  • Sources/Method: FEAF/5AF histories, target committee minutes, OR memos, JCS traffic, and press coverage; cross‑checks claims with MoE/CEP data.


🔄 Learning Over Time (within the book & vs. prior SAASS 628 cases)

  • Shifted: From decisive strategic‑attack hopes to bounded coercion and attritional interdiction/CAS.

  • Persisted: Sanctuary/coalition constraints; accuracy challenges; survivability as the operational currency.

  • (Mis)Learned: Overreliance on tonnage/bridge counts; underestimation of enemy adaptation to predictable radar‑guided approaches; partial uptake of dive‑bombing accuracy lessons. (pp. 150–154).


🧐 Critical Reflections

  • Strengths: Meticulous use of OR data and committee records; sober accounting of limits; integrated coercion narrative.

  • Weaknesses: Limited enemy archival perspective; the causal weight of air pressure on talks is argued plausibly but remains partly inferential.

  • Blind spots: Civilian harm assessment is mostly filtered through UN/US lenses; naval air’s independent logic sometimes underplayed. (p. 163).

  • Unresolved: How much earlier adoption of dive‑bombing/low‑alt profiles (with survivability enhancements) might have altered interdiction returns.


  • Douhet vs. Slessor vs. Pape/Warden (typical SAASS canon): Crane’s Korea aligns with Slessor’s constrained coercion, challenges Douhetian decisiveness, and anticipates Pape’s emphasis on denial + risk but under severe sanctuary/legitimacy constraints. Korea also tempers Warden’s system‑node logic by showing how nodes in sanctuary and external sustainment limit strategic paralysis.

❓ Open Questions (for seminar)

Instructor prompts — distilled answers:

  1. Expected role of airpower?
    US strategists (and MacArthur) expected air to isolate and destroy NK forces, deny Yalu reinforcements, and rapidly cripple industry—decisive strategic effect plus interdiction. (p. 54).

  2. Accuracy of those expectations?
    Partially right tactically/operationally (air superiority, CAS, interdiction saved the theater), but strategically overoptimistic: sanctuary/external supply blunted collapse; even MacArthur conceded over‑expectation. (p. 54).

  3. What limits emerged on employing airpower?
    Sanctuaries (Manchuria/USSR), ROE/public optics, coalition politics, weather/terrain, accuracy/CEP, enemy IADS, and resource/crew constraints. (pp. 118, 138–141, 154).

  4. How did strategists reconcile expectations with reality?
    They built target committees, moved B‑29s to night/SHORAN, revived dive‑bombing, integrated psywar/warnings, and crafted air pressure with selective high‑value strikes (e.g., Suiho) timed to talks. (pp. 118–125, 150–151, 139–140).

  5. How effective was American air employment?
    Highly effective at preventing defeat, attriting forces, and shaping bargaining leverage; not decisive alone. Coercion worked cumulatively and conditionally; MoE tied to survivability and negotiation dynamics rather than raw damage. (p. 184).

🧾 Final‑Paper Hooks

  • Claim: “Air pressure” worked as calibrated coercion—raising costs and shaping bargaining—but could not deliver capitulation under sanctuary/coalition constraints.

    • Evidence: Suiho (23 Jun 52) and PRESSURE PUMP (11 Jul 52) paired with psywar; Clark’s “max pressure lies in the air arm.” (pp. 119–125, 169). Counter: Hard to isolate air’s causal weight vs. ground stalemate and wider geopolitics.
  • Claim: Accuracy constraints (CEP; night radar) and enemy adaptation (searchlights/MiGs) forced survivability‑driven tactics that depressed MoE for interdiction.

    • Evidence: MPQ‑2 CEP ≈ 1,300 ft; SHORAN predictability; 4% pinpoint hits in 1953; June 10, 1952 losses. (pp. 138–141, 150–154). Counter: Cumulative network effects still mattered locally.
  • Claim: Coalition diplomacy/legitimacy co‑determined targeting; warnings and selective publicity were as strategic as weapons.

    • Evidence: UK protests over evacuation leaflets; State’s messaging interventions. (pp. 42–43, 123–125). Counter: Enemy propaganda minimized Western restraint benefits.
