Why telescoped ammunition has limited appeal for warships

Will warships adopt telescoped ammunition to save weight and space?

Probably not widely, because ammunition is relatively inexpensive and the space-saving advantage is smaller on warships than in many land or air platforms.

Warships still value magazine volume, but they have different space constraints from vehicles and aircraft. Navies are reluctant to trade economical, familiar shell supply for a more specialized solution without a larger operational payoff. Telescoped rounds offer their strongest advantage where every unit of protected internal volume is exceptionally expensive. A ship can usually carry conventional shells in greater numbers without accepting the procurement and integration costs of a new ammunition architecture.
