guns to −8° and elevation to 40° for "A" and "C" turrets; "B" turret was capable of depressing to −9°. At maximum elevation, the guns could hit targets out to 40,930 m (44,760 yards). The ships carried a secondary battery of twelve 15 cm SK C/28 L/55 quick-firing guns. The guns were mounted in four Drh L. C/34 twin turrets and four MPL/35 pedestal mounts. Both the turrets and pedestal mounts enabled barrel depression to −10°; the turrets allowed elevation to 40° while the pedestals limited it to 35°. These guns fired 45.3 kg (99.87 lb) shells at a rate of 6–8 per minute. They were expected to fire 1,100 rounds before barrel wear made repair or replacement necessary. The guns in pedestals had a range of 22,000 m (24,060 yd), while those in the turrets, capable of 5 more degrees of elevation, had a slightly longer range, at 23,000 m (25,153 yd). They were supplied with between 1,600 and 1,800 shells, or 133–150 shells per gun. Their anti-aircraft battery consisted of fourteen 10.5 cm C/33 L/65 guns, sixteen 3.7 cm L/83 guns, and between ten and twenty 2 cm guns. The 10.5 cm guns fired at a rate of 15–18 rounds per minute, and had an effective ceiling of 12,500 m (41,010 feet). They were mounted in six Dop. L. C/31 twin mounts amidships, and one such mount superfiring over "C" turret, which allowed depression to −8° and elevation to 80°. When used to engage surface targets, the guns had a maximum range of 17,700 m (19,357 yd) at an elevation of 45°. The 3.7 cm guns were placed in eight manually operated Dopp LC/30 twin mounts. At 85°, they had an effective ceiling of 6,800 m (22,310 ft), though tracers were limited to 4,800 m (15,750 ft). They had a rate of fire of 30 rounds per minute. After 1942, six 53.3 cm deck-mounted torpedo tubes were taken from the light cruisers and and installed on the ships, with storage for 18 G7a torpedoes. Both Scharnhorst and Gneisenau were equipped with two sets of Seetakt radar. One was mounted on the forward gun director, which was located on top of the bridge. The second radar set was emplaced on the rear main battery gun director. The Seetakt sets operated at 368 megacycles (MHz.), initially at 14 kW. The sets were later upgraded to operate at 100 kW, on
