Lightbulb Tis a Bomber


A-20 Havoc/Boston in Colour - Part 1 ..
Quote:
The Douglas A-20 Havoc (company designation DB-7) was an American attack, light bomber, intruder and night fighter aircraft of World War II. It served with several Allied air forces, principally the United States Army Air Forces (USAAF), the Soviet Air Forces (VVS), Soviet Naval Aviation (AVMF) and the Royal Air Force (RAF) of the United Kingdom. Soviet units received more than one in three (2,908 aircraft) of the DB-7s ultimately built.. It was also used by the air forces of Australia, South Africa, France, and the Netherlands during the war, and by Brazil afterwards..In British Commonwealth air forces, bomber/attack variants of the DB-7 were usually known by the service name Boston, while night fighter and intruder variants were usually known as Havoc.. An exception to this was the Royal Australian Air Force, which referred to all variants of the DB-7 by the name Boston..The USAAF referred to night fighter variants as P-70...


Servicing an A-20 bomber, Langley Field, Va., July 1942..

The DB-7s were shipped in sections to Casablanca for assembly and service in France and French North Africa..When the Germans attacked France and the Low Countries on 10 May 1940, the 64 available DB-7s were deployed against the advancing Germans. Before the armistice they were evacuated to North Africa to avoid capture by German forces.. Here, they fell under control of the Vichy government, briefly engaging the Allies during the Operation Torch..The remainder of the order which was to have been delivered to France was instead taken up by the UK via the British Purchasing Commission.. In the course of the war, 24 squadrons operated the Boston..Through Lend-Lease, Soviet forces received more than 2-thirds of version A-20B planes manufactured and a significant portion of versions G and H.. The A-20 was the most numerous foreign aircraft in the Soviet bomber inventory.. The Soviet Air Force had more A-20s than the USAAF..They were delivered via the ALSIB (Alaska-Siberia) air ferry route..By the end of the war, 3,414 A-20s had been delivered to the USSR, 2,771 of which were used by the Soviet Air Force..

The Royal Air Force agreed to take up the balance of the French order which was diverted to the UK and the bombers were given the service name "Boston", with the further designation of "Mark I" or "Mark II" according to the earlier or later engine type..Havoc I The aircraft was generally unsuitable for use by the RAF since its range was too limited for daylight raids on Germany..Havoc-Pandora Trials conducted with lone Handley Page Harrows dropping LAMs into the stream of German bombers were not successful, and the Havocs were converted back to Mk I intruders..Havoc I Turbinlite Havoc fitted with a 2,700 million candela searchlight in the nose; the batteries for it carried in the bomb bay.. Boston III DB-7B was the first batch of this model to be ordered directly by the Royal Air Force..A variation on the DB-7B/Boston III built for a French government order and featuring French instruments and secondary equipment; of the 480 DB-73s ordered by France, 240 were built by under license by the Boeing Company in Seattle..

DB-7C -This was a Dutch Indies Air Force version intended for service in the Dutch East Indies, but the Japanese conquest of the East Indies was complete before they were delivered.. Part of this order was stranded in Australia in the so-called "lost convoy", and the first 31 Bostons were assembled at Richmond Airbase in New South Wales and flown by No. 22 Squadron RAAF during the campaign against Buna, Gona, and Lae, New Guinea..The U.S. Army ordered 123 A-20As with R-2600-3 engines, and 20 more with the more powerful R-2600-11. .The A-20B received the first really large order from the Army Air Corps: 999 aircraft..The A-20J carried an additional bombardier in an extended acrylic glass nose section..The A-20K (Boston Mk V in RAF parlance) was the final production version of the A-20 series, the same as the A-20J except for R-2600-29s instead of -23s..In October 1940, the USAAC felt a need for long-range fighters more than attack bombers, sixty of the production run of A-20s were converted to P-70 night fighters, all delivered by September 1942..In 1948, the last surviving A-20H in United States service was redesignated "B-20" with the elimination of the 'A for Attack' category, and was given the "Z" prefix as being obsolete..The F-3A was a conversion of forty-six A-20J and K models for night-time photographic reconnaissance (F-3 were 3 conversions of the original A-20)...
