With the flight testing of the Mosquito prototype ongoing, official Air Ministry skepticism over the capabilities of the wooden aircraft quickly melted away and suddenly, the aircraft was required for every conceivable operational role. One of the more important roles envisioned for the Mosquito was that of high speed night fighter, to replace the aging and slow Blenheim IF and to supplement the Bristol Beaufighter.
The prototype Mosquito F Mk II (W4052) was ordered under Specification F.21/40 during 1940. This specification called for replacing the observer/bomb aimers glass nose with a solid nose containing an armament of four .303 inch Browning machine guns. Additionally, four 1 20mm Hispano cannon were installed under the cabin floor in the space normally taken up by the bomb bay. Lastly, a gun camera was mounted in the nose that operated automatically whenever the guns were tired (it could also be operated independently by a switch located next to the gun button on the control column). All armament was fired electro-pneumatically. taking air from a compressor located in the port engine nacelle.
