Supermarine Spitfire Mk.II


Brief history and description of versions:
Spitfire Mk.II aircraft differed from the previous version mainly by a more powerful Rolls-Royce Merlin XII engine. This version of the Merlin engine was started using a Coffman pyrotechnic starter. Its presence can be identified by the convex cover on the right side of the bonnet, just behind the propeller cone. Another distinguishing feature was the use of the Rotol propeller, which had wider propeller blades than de Haviland propellers, but later several dozen Mk.IIs with de Haviland propellers appeared in production.
Other noteworthy differences were improved armor weighing approximately 33 kilograms, improved coverage of the pilot's back and head, and the armor protected the coolant tank and fuselage fuel tank from the pilot.


All "two" Spitfires were made in a new "shadow" factory in Castle Bromwich. A total of 750 machine gun Spitfires were built Mk.IIA and 170 cannon Mk.IIB. The original order was agreed for 1000 Spitfires Mk.II, but the last eighty produced aircraft were already delivered in a version Mk.VA and Mk.VB.


It is also worth mentioning the Type 375 modification, it was 49 (sometimes 50 - 52) aircraft adapted for air rescue service. The armament was reduced and a dinghy lifeboat and an emergency supply of food and water were hung under the wings. The plane was still carrying smoke bombs, which could indicate the position of the uncleaned pilot. This modification was marked as Mk.IIC, later these aircraft were redesignated to Spitfire ASR Mk.II (Air Sea Rescue). Some of these rescue Spitfires were probably given to engines Rolls-Royce Merlin XX.
About sixty aircraft were modified into a long-range escort fighter Spitfire LR. Mk.IIA.
