Avro 523 Pike
|Role||Multi-role military aircraft|
|First flight||May 1916|
The Avro 523 Pike (the first Avro aircraft to receive a name) was a British multi-role combat aircraft of the First World War that did not progress past the prototype stage. It was intended to provide the Royal Naval Air Service with an anti-Zeppelin fighter that was also capable of long-range reconnaissance and light bombing.
Design and development
The Avro Pike was a large, three-bay biplane of conventional layout driven by two pusher propellers. Three open cockpits were provided, the centre one for the pilot, and gunners fore and aft of him. The Admiralty evaluated the type, but rejected it. Avro then built a second prototype, changing the original's Sunbeam engines for Green E.6 engines instead and designating it the 523A.
The Admiralty evaluated this in November 1916, but found that the type was now obsolete and did not place an order. The two prototypes flew as testbeds with Avro for the remainder of the war.
