Kriegsmarine Carrier Weser (Carrier conversion of Seydlitz Heavy Cruiser)
conversion work would have slightly increased the ship's length to 216 m (708 ft 8 in) long overall, but decreased her draft to 6.65 m (21 ft 10 in) at full load. Her propulsion system, which had already been installed, would remain the same, as would her expected performance. A large island was to be installed on the starboard side, with a tall, tubular mast on the forward end of the island.
The flight deck was to have been 200 m (660 ft) long and 30 m (98 ft) wide. The hangar was 137.50 m (451.1 ft) long and 17 m (56 ft) wide forward and 12 m (39 ft) wide amidships and aft. Two elevators would have been installed to transfer aircraft from the hangar to the flight deck. Seydlitz's air complement was to have consisted of ten Bf 109 fighters and ten Ju 87 Stuka divebombers. The Bf 109 fighters were a navalized version of the "E" model, designated as Bf 109T. Their wings were longer than the land-based model to allow for shorter take-off. The Ju 87 type selected was to have been the "E" variant, which was a navalized version of the Ju 87D, and were modified for catapult launches and were equipped with arresting gear.
Her armament was reduced to a medium-caliber anti-aircraft battery of ten 10.5 cm L/65 guns in twin mounts, two forward of the conning tower and three aft. All of these would have been in line with the island, in a superfiring arrangement. The LC/31 mounting was triaxially stabilized and capable of elevating to 80°. This enabled the guns to engage targets up to a ceiling of 12,500 m (41,000 ft). Against surface targets, the guns had a maximum range of 17,700 m (58,100 ft). The guns fired fixed ammunition weighing 15.1 kg (33 lb); the guns could fire HE and HE incendiary rounds, as well as illumination shells.
These would have been supported by a battery of light anti-aircraft guns consisting of ten 3.7 cm guns in dual mounts and twenty-four 2 cm guns in quadruple mounts. These were distributed along the sides of the ship, generally on platforms that overhung the sides of the ship. Four of the 3.7 cm mounts were on the sides of the ship and the fifth mount was on the extreme bow. Two of the 2 cm mounts were to be placed on the island, with the remainder in the side platforms.[18] The mounts were the Dopp LC/31 type, originally designed for earlier 8.8 cm (3.5 in) SK C/31 guns. The 3.7 cm gun was a single-shot gun, with a rate of fire of around 30 rounds per minute. At its maximum elevation of 85°, the gun had a ceiling of 6,800 m (22,300 ft). The 2 cm gun was a magazine-fed automatic weapon, firing at up to 500 rounds per minute. Twenty and forty-round magazines were supplied for the guns
