ABSTRACT:
A launchable a fin-stabilized round having an HE warhead that is fully telescoped in a cartridge case. The round has a forward, cone-shaped nose section, a base section with a booster cavity and a high-explosive (HE) cavity located therebetween. An HE charge is positioned in the HE cavity and a booster charge is positioned in the booster cavity. A time fuze, mounted in the booster cavity, has a presettable counter that is set by the gunner at firing via a hardwire data link through an electric primer. The tiem fuze will fire the booster charge a predetermined time period after the round is launched to enable a normally disabled proximity fuze that is mounted in the nose section. The proximity fuze will detonate the HE charge upon detection of a proximate target. Also mounted in the nose section is a contact switch for detonating the HE charge upon impact with a hard target.
