In 1942, Martin-Baker Blackburn produced a multi-role naval aircraft, powered by the twin-Perseus, capable of performing the roles of fighter, bomber, torpedo carrier and scout/patrol, employing a centerline stores station for 18" torpedo, up to 2000 lb bomb, or 90 gal fuel tank, along with alternate or combined wing mount loads rated for 1000 lb bombs or additional fuel, or 8 anti-ship rockets. Built in armament is 4 20mm cannon with up to 200 rpg. depending on mission. Nobody made an aircraft more easily maintained, serviced, and repaired than James Martin, and yes, the ammunition bay doors were upholstered so that armorers could be comfortable while they re-armed the cannons. The reliability and low maintenance requirements of the Bristol engine was another factor in it's favor. The radio was of American manufacture, and had a built in homing function, good range, and superior reliability. The cockpit was roomy and comfortable, particularly by British standards, and visibility was rated good. The powered wing-fold mechanism worked flawlessly. Eric Brown rated take-off and landing characteristics as well above average, easily accomplished with median skill levels. Contracting the Martin-Baker company to design Blackburn aircraft, and employing the aerodynamicist, Ben Shenstone, resulted in a multi-mission weapon unequalled, at the time, in performance and versatility. It remained for the Ministry to make a recommendation regarding it's production and use.
