The RPG-28 is the latest and most modern rocket-propelled grenade in use by Russian army. It was designed to defeat most modern and even the future main battle tanks with composite / reactive armor, as well as enemy personnel behind thick stone or brick walls (penetration against the brick wall is about 300 cm / 10 feet). It is also offered for export.

The RPG-28 is a disposable, single shot rocket launcher pre-loaded with fin-stabilized rocket. The single-piece smoothbore barrel / container is made of fiberglass. The rocket is contained in the barrel tube, and its solid-fuel motor burns out completely within the barrel. Because the barrel is open at the rear to avoid recoil, there is a dangerous backblast area behind the firing weapon. In transport/storage mode both ends of the barrel are closed by the front and rear covers, made of rubber; those covers shall not be removed manually and are destroyed during the rocket launch. Firing mechanism is cocked manually by rising the rear sight; lowering the rear sight de-cocks the firing mechanism so the grenade can be brought back to safe mode if the there's no immediate target. The launcher tube is also equipped with standard sight rail which can accept telescopic or IR / Night sighting equipment. Since the complete system is quite heavy, it is equipped with shoulder pad below the center of mass, a folding support leg (monopod) at the rear and a folding forward grip in front. The rocket is fin-stabilized (with six switch-blade like fins at the rear), and its solid-propellant motor burns out completely while rocket is still in the barrel. The tandem, dual shaped charge (HEAT) warheads capable of defeating modern and future reactive armor plus at least 1000 mm of homogenous steel armor behind it.
