Two 4.0 m (13.1 ft) diameter, 3.6 cm (1.4 in) thick high-strength low-alloy steel pressure hulls connected by a 1.45 m (4.8 ft) tunnel. Pilots and observers are housed in the forward hull with mechanical and power supplies in aft hull. A 1.7 m (5.6 ft) escape sphere was mounted on the forward hull. Access was through four 500 mm (20 in) hatches with one 600 mm (24 in) emergency escape hatch. Five view ports with 90° viewing angle in the forward sphere, three 120 mm (4.7 in) inside diameter for forward viewing and one 50 mm (2.0 in) inside diameter on each side.[1]
