Hi SR.
Just wondering if you compiled the list of bombers on page one based on Mason's book (The British Bomber - Putnam 1994) as it chronologically fits perfectly, minus a few experimental types. I could be wrong.
Mason seems to have taken over from the the same titled book in the Putnam range but which was published originally in the late 60's and written by Peter Lewis.
Lewis made it clear on the front inner dust-jacket that he considered just about any aircraft that could carry a bomb/s or torpedo - as a bomber. I don't agree with the definition, but it's their books.
Yes I used the that book, it is rather convenient for this sort of thing.
I have my own "definition"of a bomber, much like the proverbial duck.
If it walks like duck, quacks like a duck and swims like a duck, it's a duck. (bomber)
Some are bigger than others, some are faster than others. Some had other duties incorporated in their specifications.
The HP Harrow equipped 5 bomber squadrons from the end of 1937 (all in Britain) until the last gave them up at the end of 1939. All were replaced by Wellingtons.
In 1937 the Germans were using a number of Ju 52s as bombers so this is not really a dig at the British. The Bristol Bombay was the design contemporary of the Harrow but due to delays (understandable in the light of building a new factory in Northern Ireland) production didn't start until sufficient Wellingtons (and Hamptons) were being built and the Bombay went off to it's secondary roll as transport.
I don't believe anybody ever contemplated operating the Harrows in daylight so the question of a suitable escort is rather moot.
In regards to the Lysander, no it was not a "conventional bomber". It falls more into the catagory of ground attack/close support aircraft. Yes, this duty was one of many it was tasked with.
But you don't wind up with the machine gun and bomb armement it had by accident on a battlefield photo-recon plane.
British ground attack/close support aircraft had a long and rather twisted development (or rather development at times was left to twist in the wind). The RAF had certainly performed trench strafing/light bombing in WW I and had built several specialized types (Sopwith Salamander for one) for this duty. However between budget cuts and changes in policy the official position on such aircraft tended to go back and forth?
Getting to the mid to late 30s and 3-5 years between initial requirement and squadron service the Lysander had the same (or slightly better ) bomb load/capacity as the Audax that it was to replace.
Lets also remember the whole Audax, Hardy, Hind family. Same wingspan, same length, same wing area (same wings?) perhaps a different mark Kestrel in the nose, similar two seat cockpit, same ,303 Vickers gun in the side of the fuselage and same Lewis gun in the back. Each them
could carry about 500lbs worth of bombs but the Audax was an
"army cooperation biplane", the Hardy was a "general purpose biplane" and the Hind was "light day bomber biplane". Actual difference was the type of equipment in and around the cockpit/s (?) so hopefully the casual observer is forgiven about what constituted "a bomber" under the "
whether or not the aircraft was intended for and operated by RAF Bomber Command" definition.
Apparently the Hardy, to suit the "General purpose" classification was an Audax with an emergency tent, bedding, food and drinking water (wireless removed?), low pressure tyres for rough dessert landing strips and improved cooling for tropical conditions.
The Lysander had about three times the firepower for strafing than the planes it replaced.
We also have the Fairey P.4/34, from wiki
" In
1934 the
Air Ministry issued
Specification P.4/34 which called for a light bomber that could also be deployed in a
close-support role.
Fairey,
Gloster and
Hawker all supplied proposed designs; contracts were issued for the construction of examples of Hawker and Fairey's designs. The P.4/34 design was a low-wing all-metal
monoplane, powered by a
Rolls-Royce Merlin engine, with a crew of two accommodated in tandem under a long-glazed
canopy. Its layout was similar to Fairey's earlier
Battle bomber, but the P.4/34 was smaller and had a wide track, inwards-retracting
undercarriage. The aircraft was stressed for
dive bombing, as required by the specification, and carried its load of two 250 lb (110 kg) bombs underwing (the competing Hawker aircraft had an internal bomb bay). "
Now I don't know who was supposed to operate the Fairey airplane or Hawker Henley but if it wasn't "Bomber Command" then they aren't bombers?????
This design competition shows that the RAF/Air Ministry certainly didn't believe that the Battle was ideal for close support. Doctrine/policy could certainly shift in the 3-4 years between issuing the request for designs and planes being able to be built. The bomber boys may have desired to kill off the close support program as distracting (taking away from) bomber commands true mission.
This left the Lysander as the defacto close-support aircraft.
