Blackburn Skua

The Blackburn Skua was a carrier based dive bomber used by the Royal navy during the early stages of World War 2.
==History==
The Skua was designed to meet specification 0.27/34 for a navel dive bomber. Page 20
The first prototype Skua had problems with stability and it and the second prototype (both known as Skua MK Is) had to be modified with a longer nose and upturned wingtips, features carried over to the production aircraft (known as Skua Mk IIs). The Skua prototypes used the well tried Bristol Mercury engine but use of these engines in the huge Blenheim bomber programme meant that production Skuas had to use the new Bristol sleeve valve Perseus engine. There is no evidence that the Perseus engine as used on the Skua was particularly unreliable in itself, (later Bristol sleeve valve engines, paricularly the Taurus, went through a stage of very bad reliability when first mass-produced by unskilled labour, faults cured in the supremely reliable later model Hercules and Centaurus) but the new sleeve valve technology must have made maintenance more difficult and the Perseus's small production run must have made spares hard to find as the war years rolled by. The spin characteristics of the Skua were bad enough to prompt the fitting of an anti-spin parachute in the tail to aid recovery. 
The Skua was built to Specification O.27/34 issued in 1934, two prototypes were ordered in 1935 and the first prototype (K5178) did not fly until nearly two years later on 9th Feb 1937. In October of that year it went for handling trials at A.&A.E.E. Martlesham. The second prototype (K5179) did not fly until 4th May 1938, and the first production Skua (L2867) flew on 28th August 1938. A total of 190 Skuas had been ordered as far back as July 1936, even before the first prototype had flown. Thus production was started a full two years after the order. However deliveries were prompt after that and over 150 had been delivered by the time War started, with all but one being delivered by the end of 1939. This meant that the Skua was very much a "new" aircraft when it first went to war and its pilots were still finding their way in this big metal monoplane aircraft with retractable undercarriage and enclosed cockpits, all a novelty to British carrier pilots of the time. It is interesting to speculate what might have happened if the original expected "in-service" date of 1937 had been kept to. Then the crews would have had two years to get to know their aircraft and the Navy would probably have had 4 or 5 fully equipped and trained Skua Squadrons "ready to go" at the outbreak of war. There would probably have been follow-on orders for a second production run, maybe another 100 or so aircraft, perhaps incorporating minor improvements. As it was the Skua was viewed as obsolete from the start of it's service career and many of the later Skuas were clearly destined never to have a combat role, being delivered from the factory fully equipped as target tug trainers in a yellow and black striped livery.John Dell Main Skua Page
