The 5th Air Force operated under General George C. Kenney across the Southwest Pacific — from Australia and New Guinea through the Philippines and Okinawa.

This 5th Air Force markings reference covers the identification systems used by USAAF units across the Southwest Pacific Area (SWPA) — tail numbers, group insignia, squadron colors, and individual aircraft markings for every bomber, attack, and fighter group that operated from Australia, New Guinea, the Philippines, and Okinawa. Activated on 5 February 1942 under Maj. Gen. Lewis H. Brereton and later commanded by Lt. Gen. George C. Kenney, the 5th Air Force became the most experienced and longest-serving American air force of the Pacific war.

Unlike the European-based 8th and 15th Air Forces — which used standardized wing-level geometric symbols — the 5th AF relied on group-level insignia, white tail identification numbers, and prolific individual aircraft nose art. Its heavy bomber groups flew B-24 Liberators on long-range strategic strikes, while its medium and attack groups pioneered devastating low-level tactics with B-25 Mitchells and A-20 Havocs modified as strafers. Fighter groups flew P-38 Lightnings — the signature fighter of the Pacific — P-40 Warhawks, P-47 Thunderbolts, and P-51 Mustangs.

The 5th AF’s groups fought from the desperate early days of the war — defending Australia and Port Moresby in 1942 — through the offensive campaigns in New Guinea, the Philippines, and the final strikes against the Japanese home islands. Its units produced America’s top two aces, Richard Bong (40 victories) and Thomas McGuire (38 victories), and pioneered the skip-bombing, strafing, and low-altitude attack tactics that defined Pacific air warfare.

How 5th Air Force Markings Worked

The 5th Air Force had no standardized wing-level marking system like the 8th or 15th Air Forces. Instead, identification was handled at the group and squadron level through a combination of tail numbers, group-specific insignia, squadron colors, and individual aircraft nose art. The result was one of the most colorful and varied marking schemes of any USAAF air force.

Bomber & Attack Markings

Heavy and medium bomber groups used white tail identification numbers (typically the last three digits of the aircraft serial number) as their primary identification. Group-level insignia — like the 90th BG’s skull and crossbones or the 345th BG’s Apache head — were painted on fuselages or tails. B-25 strafers received extensive field modifications and individual nose art was widespread.

Fighter Markings

Fighter groups used squadron-color spinners, cowling bands, and tail boom markings (on P-38s) for identification. White tail numbers were standard. Individual kill markings — Rising Sun flags painted below the cockpit — were widespread. Squadron insignia (like the 80th FS “Headhunters” skull) were painted on fuselages or engine nacelles.

Theater Identification

The SWPA had no theater-wide marking system comparable to the ETO’s invasion stripes. White identification numbers on dark OD/NG aircraft served as the primary recognition marking in the early war. During amphibious operations (Leyte, Luzon), some aircraft carried temporary white recognition bands. By late 1944, natural metal finish aircraft relied on unit markings alone for identification.

Key Aircraft Types

The 5th Air Force operated eight primary aircraft types during its campaigns across the Southwest Pacific, 1942–1945.

P-38J/L Lightning

Fighter / Escort

The signature fighter of the 5th Air Force. The twin-boom Lightning's range — over 1,100 miles with drop tanks — made it ideal for the vast distances of the Pacific. Its twin engines provided critical reliability over open ocean. Flown by the 8th, 49th, and 475th FGs, the P-38 produced most of the 5th AF's aces, including Richard Bong and Thomas McGuire.

B-24H/J Liberator

Heavy Bomber

The primary heavy bomber of V Bomber Command. Flown by the 22nd, 43rd, 90th, and 380th BGs on long-range strategic strikes against Japanese bases, oil refineries, and shipping. The B-24's exceptional range (3,000+ miles) was critical in the Pacific, enabling missions to targets like Balikpapan in Borneo.

B-25 Mitchell

Medium Bomber / Strafer

The most versatile aircraft in the 5th AF. B-25s were extensively field-modified as low-level strafers with up to 14 forward-firing .50-caliber guns packed into solid noses. The 3rd AG, 38th BG, and 345th BG used these deadly strafers to devastate Japanese shipping, airfields, and troop concentrations at treetop level.

Learn more about this aircraft

P-47D Thunderbolt

Fighter-Bomber

Late-war addition to the 5th AF, flown by the 58th and 348th FGs and as a replacement aircraft for the 35th and 49th FGs. The Thunderbolt's ruggedness and heavy armament made it effective in the ground-attack role across the Philippines.

Learn more about this aircraft

P-40E/F Warhawk

Fighter

The early-war fighter of the 5th AF. P-40 Warhawks defended Australia and Port Moresby during the critical 1942–43 period when newer fighters were unavailable. The 49th FG flew P-40s during some of the most desperate air battles of the Pacific before transitioning to P-38s.

Learn more about this aircraft

A-20G/J Havoc

Attack Bomber

Fast, low-level attack bomber flown by the 3rd AG, 312th BG, and 417th BG. The A-20G had a solid nose with 6x .50-cal forward-firing guns, making it a devastating strafer. Used for skip-bombing, para-frag attacks on airfields, and direct close-support of ground troops across New Guinea and the Philippines.

Learn more about this aircraft

A-26B/C Invader

Attack Bomber

Successor to the A-20 Havoc, first flown in combat by the 3rd Bombardment Group from Hollandia, New Guinea in June 1944 — the A-26's combat debut. Faster and more heavily armed than the A-20, with up to eight .50-cal nose guns and 6,000 lb bomb load. Used for low-level strafing and bombing through the Philippine liberation campaign.

Learn more about this aircraft

P-39D/N/Q Airacobra

Fighter

Flown by the 8th and 35th Fighter Groups in the defense of Port Moresby, New Guinea, during the critical 1942 period. The P-39's limited ceiling hampered high-altitude interception, but its 37mm cannon was effective in ground attack. The 35th FG's 'Black Panthers' flew P-39s before transitioning to P-47 Thunderbolts.

Camouflage & Paint Schemes

5th Air Force aircraft experienced some of the harshest environmental conditions of any USAAF theater — tropical heat, monsoon humidity, jungle dust, and coral airstrip abrasion.

Tropical Camouflage (1942–43)

Early-war aircraft wore standard ANA 613 Olive Drab over ANA 603 Neutral Gray. The intense tropical sun caused OD paint to fade rapidly — far faster than in the European theater — producing a distinctive greenish-tan or almost khaki appearance. Some aircraft arriving from Australian depots carried Dark Earth upper surfaces or mixed camouflage from RAF-pattern stocks. Fungus and algae growth on parked aircraft was a constant problem, leaving organic staining on fabric control surfaces and in panel line crevices.

Modeling note: Pacific OD faded more dramatically than European OD. The bleaching effect of tropical sun created a warm, tan-green tone rather than the darker OD seen on ETO aircraft. Mix progressively lighter and warmer tones to capture this effect.

Natural Metal Finish (1944–45)

The transition to unpainted NMF aircraft began in late 1943 and accelerated through 1944. In the humid Pacific, bare aluminum showed corrosion more quickly than in Europe, and maintenance crews applied zinc chromate primer to vulnerable areas. Unit markings — white tail numbers, group insignia, squadron colors — were applied directly to bare metal. Anti-glare panels on engine cowlings and forward fuselages were painted flat black or OD.

Modeling note: Pacific NMF aircraft showed more corrosion, exhaust staining, and oil streaking than their European counterparts due to the tropical climate. Coral dust from Pacific island airstrips created distinctive orange-pink deposits on lower surfaces and wheel wells.

Modeling 5th Air Force Aircraft

Building a 5th Air Force subject offers modelers some of the most dramatic and characterful subjects of the war — from P-38 Lightnings over New Guinea to strafer B-25s at wave-top level.

Pacific P-38 Details

  • • Twin-boom configuration means markings were applied to booms, central nacelle, and wing surfaces. Squadron colors appeared on spinners and sometimes boom tips.
  • • P-38s carried 165-gallon or 300-gallon drop tanks on nearly every mission. Include tanks for any operational subject.
  • • Kill markings (Rising Sun flags) were painted below the cockpit on the port side of the nacelle. Richard Bong’s P-38 carried 40 flags.
  • • Exhaust staining on the P-38 appeared along the inner surfaces of both booms from the turbo waste gates.

Strafer B-25 Modifications

  • • Field-modified solid noses packed with 6–14 forward-firing .50-caliber guns replaced the bombardier’s glazed nose on many 5th AF B-25s.
  • • Additional gun packs were mounted in fuselage cheek positions and on the sides of the nose. These field modifications varied by group and squadron.
  • • Para-frag bombs (small fragmentation bombs on parachutes) were carried in the bomb bay for low-level airfield attacks. Skip-bombing modifications included special bomb racks.
  • • The 75mm cannon nose (B-25G/H) saw limited use in the SWPA for anti-shipping strikes.

Tropical Weathering

  • • Humidity caused far more paint deterioration than in Europe. OD paint blistered, flaked, and faded to near-khaki within weeks of application.
  • • Coral dust from crushed-coral airstrips (common throughout the Pacific islands) left distinctive orange-pink deposits on gear doors, wheel wells, and lower fuselage.
  • • Monsoon conditions meant mud splatter from unpaved revetments and taxiways. New Guinea airfields were notoriously muddy.
  • • Salt spray corrosion affected aircraft operating from coastal airstrips. White salt deposits appeared on bare metal surfaces.

Nose Art & Individual Markings

  • • The 5th AF was arguably the most prolific source of nose art in WWII. The combination of long deployments, artist talent, and relaxed regulations produced some of the most elaborate artwork of the war.
  • • Individual aircraft names were nearly universal — far more common than in the 8th AF, where squadron codes took visual precedence.
  • • Mission tallies (small bomb symbols for bombing missions) were painted near the cockpit. The 90th BG and 345th BG aircraft carried particularly elaborate mission markings.
  • • Kill tallies for confirmed aerial victories used small Japanese flag (Rising Sun) symbols. Ground kill tallies used different symbols.
