As built, the test vehicle had only 26 rounds, but provisions existed for the original 60 rounds in the turret. [8] The projectiles were stored vertically in a magazine beneath the right side of the turret and fed vertically into the rotating breech, with the shell casing being ejected vertically upwards.

The shells of the sea snails in this family are typically shaped like slender augers or screws. In that respect they share certain shell characters with the family Turritellidae, the turret shells. One characteristic that distinguishes Terebridae from Turritellidae is the short anterior canal or notch in the aperture of the shell.
Alternatives included the heavily-armoured gun turret and an armoured, fixed central gun battery. By the late 1880s, all three systems were replaced with a hybrid barbette-turret system that combined the benefits of both types. The armoured vertical tube that supported the new gun mount was referred to as a barbette.
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree ...
The turret extended either four decks (Turrets 1 and 3) or five decks (Turret 2) down. The lower spaces contained the equipment required to rotate the turret and to elevate the guns attached to each turret. At the bottom of the turret were rooms which were used for handling the projectiles and storing the powder bags used to fire them.
The Jaguar is designed to offer STANAG 4569 Level 4 armour protection as standard, capable of withstanding 14.5 mm armour-piercing ammunition, 155 mm artillery shell splinters, IEDs and mine blasts. [31] In addition to the thickness of the armour, the underbody architecture has been designed around hard points that "reflect" the blast effect ...
Ideally, these caps have a blunt profile, which led to the use of a further thin aerodynamic cap to improve long-range ballistics. Armour-piercing shells may contain a small explosive charge known as a "bursting charge". Some smaller-calibre armour-piercing shells have an inert filling or an incendiary charge in place of the bursting charge.
Obsolete Type 88 shells were modified in 1939–40 to create the Type 99 No. 80 Mk 5 armor-piercing bomb used during the attack on Pearl Harbor. [9] The armor-piercing cap and windscreen were removed, the body was machined down and tapered to reduce weight and a new, thinner, base plug installed with two fuzes . [ 9 ]
