    Interpreting wartime photography: Catalina in Ceylon

    While most people only really recognise 2 models of the Catalina, the PBY-5 flying boat config and the PBY-5A Amphib. config (later PB2B-2 and PBY-6A big tails) the Catalina evolved under the skin continually during the war, Engine, Radar, guns, underwing stores, MAD detection, etc, it was one of the only aircraft during the war that served the whole war in its basic airframe config without major structural changes.

    Yep, when they were upgraded to the later radar , some retained the main antenna mounts under the wings, , the small antenna outboard on the right wing was removed and the multiple small horizontal antenna bars were removed from the main antenna arms, Catalina's upgraded may have the underwing antennas but late PB2B-1's and PB2B-2's (Big tail Catalina's) with the radar above the cockpit from the factory didn't have any trace of the old style antenna's.

    The photo of the Catalina in Karachi getting the engine worked on , the Cat in the background is a late IVB with an eyeball nose turret, late style radar housing over cockpit and a Leigh light under the right wing, JX431 COULD be in this config or the earlier single gun nose turret and under wing Radar antennas, unless you have a pic of the front of the aircraft or the history of the aircraft anything is possible.

    2 is better than 1 , the RAF didn't put a lot of effort into upgrading armament , still had there heads in a dark place persisting with .303's, Australian, Canadian and Norwegian Sqn's all went to lengths to add extra guns to their Sunderland's and Cats but RAF Sqn's were stuck with inadequate armament .

    Interpreting wartime photography: Catalina in Ceylon

    This aircraft JX 431 is a late model Catalina IVB's (PB2B-1's), these were only delivered in 1944 from the factory, they were configured to very late model PBY-5 specs with heated leading edges with the exhaust heat exchanger (no black leading edge boots on wings or tail), these Catalina's came with .50's in the waist position not twin .303's like earlier RAF Catalina's, machines in Europe usually had the std nose turret with 1 x ,303 in it rather than the 2 x .303 "eyeball" turret(for some reason the RAF didn't push to have these fitted despite the U-boat AA menace), 6 x PB2B-1's to the RAAF and 34 to the RNZAF in similar serial Blocks all had twin gun nose Eyeball turrets fitted, also these later Catalina's usually had the later ASV radar in the pod over the cockpit not the underwing aerials array, they were in the std late Coastal scheme of EDSG over white which faded very badly in the tropics (the RNZAF operated there's in this scheme , the RAAF repainted theirs Black before issue to Sqns)

    More Help with RAAF Catalinas particularly Ordnance ?

    The torpedo rack mentioned by Magpie (Pete) is also what the mines were carried with, the photo of the Catalina with 2 x different mines the one under the left wing looks to be a US Mk 25 @2000 Ib , the one under the Right wing is a British Mk IX mine @ about 1800 Ib. From Mines Away! The Significance of U.S. Army Air Forces Minelaying in World War II By Major John S. Chilstrom. Initially flying from Australian bases at Darwin and Cairns, then from captured island airfields, three squadrons of RAAF PBY-5 Catalinas laid mines in key enemy harbors in the Southwest Pacific. Australian aerial mining began April 22, 1943 when eight aircraft laid sixteen magnetic mines at Kavieng, New Ireland. Those mines, and others at Lorengau in the Admiralty Islands, convinced the Japanese to abandon fleet achorages there after mines sank five ships and damaged seven Others. In August 1943 the RAAF flew over 1,000 miles to attack the headquarters for Japan.s Second Southern Expeditionary Fleet at Surabaya. Their mines sank seven ships, and damaged eleven. On this, and other, long-range flights, the Catalinas extended their reach by refueling with U.S. Navy seaplane tenders on the return route. For the next two years the Australians flew missions throughout the Netherlands East Indies, including New Guinea, Halmahera, Celebes, Java, and Borneo. Additionally, in 1944, they laid mines to support amphibious landings in the Carolines, Marshalls, and Philippine Islands. Ultimately the RAAF extended their reach as far north as the Chinese coast, while still mining all major harbors in the East Indies. The PBY-5 Catalinas used by the RAAF were amphibious aircraft that provided good results. The aircraft was well suited to minelaying, with long range and a payload of 2,000-4,000 pounds. Out of 1,130 successful sorties that laid 2,498 mines, the Australians lost nine aircraft, a 0.8 percent loss rate. Altogether, the postwar U.S. Strategic Bombing Survey estimated these mines sank 90 ships total ling 250,000 tons, or approximately 40 percent of Japanese losses in the Netherlands East Indies. The report said mine laying Catalina's were 10 x times more effective than conventional bombers and attack aircraft in the anti shipping role in the SW Pacific.

    Disregard previous post , did a bit of research and Voila ! US 500 Ib bombs with single and double lug , I would have deleted the post but no delete button!

    Dennis, what time frame are you using for the aircraft, with the depth charges the Mk VII 450Ib DC was all but replaced by early 1942 in Europe with the Mk VIII 250 Ib DC, the 450 Ib had a very restricted drop parameter, and was proven ineffective on Uboats , it was very much a stop gap measure till the 250 Ib was developed, the photo's I have seen of RAAF Cats in the pacific they were carrying 3 x 250 Ib DC's under each wing, Bombs , thru 42-43 mainly British style , after that either US or British , Bombs made in Australia were to a British pattern but had two threaded inserts on one side for the mount points to fit US bomb Racks and a single insert on the other side of the casting to fit British bomb racks, I have photo's of latter Black cats with 4 x US 500Ib's and early Cats with 8 x Brit 250 Ib bombs. Torpedo's, both US and UK types trialled but not used operationally . Mines , the main weapon of the RAAF Cat latter in the war, If a mission with multiple Cats was going to mine a target eg 4-5 aircraft in the one night, half would carry US mines and half British mines, if a single Cat was doing the mining over many nights it usually carried one of each , the British and US mines had different methods of setting them off and required different sweeping techniques, hence the Japanese lost ships on what they thought was a cleared field which had mixed types. mines 1600-1800 Ib each Cats carried 1 x under each wing on the inboard hardpoint.

    A20 Havoc / Boston

    I assume you are talking about the RAAF 22 Sqn Boston III "Spirit Of Sport", this is a std DB-7B Boston III in the standard RAF scheme of DG/DE over sky, all Boston III's run the same engine cowl , the "Tropical" cowl is made by simply removing 6 oval cooling hole covers from the lower outer engine cowl and 2 from the lower inner cowl (total 8 oval holes). Red Roo make a 1/48 Tropical engine cowl set for the A-20A and DB-7B (Boston III). "Spirit of Sport" A28-15 DU-Q was a DB-7B Boston III (RAF serial AL361)(Boeing built) and was nominaly Flt Lt Bill Newtons aircraft though he only flew it on 2 missions before he was lost and not on his VC mission on 16 Mar 43 as has been incorrectly stated in alot of publications and articles, it was lost on a mission to New Britain on 14 Sep 43. This aircraft flew 56 missions till it was lost and was flown on most missions by Flt Lt Bob Wines (more than 30) who took it over as his aircraft after Bill Newton was lost . It had the single letter code of "Q" between Nov 42 and Jul 43 and the DU Sqn ID code was applied mid Jul 43. 4 x .50's thru the bomb aimers window and the std 4 x .303's in the cheek positions. Strafer Bostons had their bomb load reduced to 1500 Ibs from 2000Ib , as the 4 x .50's with mounts and ammo added more than 500 Ib to the nose of the aircraft (.50 MG weighs 80 Ib each and 100 rounds of .50 ammo weigh 35 Ibs) (4 x .50 and 1000 rounds of .50 ammo (250 per gun) and mounts= approx 700 Ib). Normal bomb load on a Boston III Strafer was 2 x 250 Ib (fwd position in bomb bay) and 2 x 500 Ib bombs (aft position in bomb bay).

    A20 Havoc / Boston

    The Italeri P-70 kit is good and accurate, the A-20B/C kit is accurate for the French Boston IIIA (A-20C) or the A-20B but doesn't have the correct early engine cowls with the single exhaust for the RAF Boston III (DB-7B).

    A20 Havoc / Boston

    Jerry, about a 12/13 options for each of the 3 A-20/Boston/Havoc sheets, almost every aircraft ID'd by photo's, I helped Franta with the research, couple of Mediterranean 18Sqn machines will get some comments. A couple more A-20 sheets to go for other theatre's /users.

    A20 Havoc / Boston

    1/72, MPM for A-20B , A-20C , Boston III/IIIA, A-20G/H, Revel do the A-20J/K from MPM but they have tweaked it a bit, more detail in turret and a couple of other small things. DK decals are about to release a couple of great sets of A-20/Boston decals, lots of interesting markings.

    Hurricane IIB Burma AP894 135 Sqn Jack Storey roundels?

    Thanks Claudio the fuselage roundel does look like a std C1 with the red painted out. I have photo's of 3 of Jack Storey's Hurricannes, his second Hurricane , WK-C (L/H side picture C-WK) (R/H side pic WK-C) Hurricane IIA Z5659, 3 + 2 prob kills a later IIB Std markings with red (photo L/H side C fwd of Roundel) BN163 , no kills and his last IIB interim SEA markings ( Photo R/H side C fwd of roundel) AP894, 4 kills . Its this last Hurricane I am tracking down the wing roundels for.
  15. I am trying to Id wing roundels for the last Hurricane Jack Storey flew in Burma , a Mk IIB AP894 it has the interim fuselage roundel applied in Burma with the C1 with the red over painted over with std fin flash and "C" in medium Sea Grey fwd of the roundel on the right and ? on the left (assume fwd), the info I can't find are the wing roundels in the transition period, its hard to confirm what wing roundels are applied , Mohawks in the similar timeframe appear to have had the upper wing red painter white in the type B and the red dot over painted white in the lower type C. Was the Hurricane the same?
