Design
The total barrel length of the 100 TK is 5608 mm. The maximum range is about 18 km. The sustained fire rate is 6 rounds per minute and the muzzle velocity is 880 m/s with HE-FRAG shells. The breech block weighs 63.4 kg. The breech mechanism is semi automatic and the gun is loaded manually. Guns were modified for a higher maximum elevation and necessary equipment for indirect fire was added. Since the turrets were intended for coastal fortifications the turret insides were coated with asbestos-cork mixture to prevent moisture from condensing into gun position. Messaging, electric and ventilation systems were left mostly intact. A fully automatic loading system would have taken too much space, and simple counterweight operated shell hoisting mechanism was developed to transfer ammunition up to the turret.

Famous quotes containing the word design:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”

“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
