This weapon entered service in mid-1944 with patrol craft and was later fitted to larger units. Used a single-barrel projector. Several different kinds of shells were produced, including HE, smoke and wire cable. Each HE rocket had the destructive power of an 8.8 cm AA shell. The wire cable version was similar to the British UP AA rocket and used parachutes connected to 100 m (330 feet) of cable. It is not known if these weapons ever shot down an attacking plane.
The operational technique was to establish three concentric zones around the ship, with each zone given a specific rocket type. These were stored in ready-use lockers close to the launchers.
It is interesting to note that the parachute version of this weapon was similar to the ineffective British UP AA rockets. That weapon was withdrawn from service following the loss of HMS Hood.

- ^Other types of rockets for special purposes such as smoke-marking and signalling were proposed or manufactured but the fleet objected to the profusion of types. The ones listed above were the main variants actually carried by warships.

- ^Starshell burned for 30 seconds.
- ^As noted above, the operational concept was to establish three concentric zones around the ship. Close to each launcher were ready-use lockers. Each locker contained three rows of five rockets each. Row 1 had R.Dg 1000 for Zone 1; Row 2 had R.Dg. 400 or R. Spg. 800 for Zone 2; Row 3 had R. Spg. 400 for Zone 3. Zone 1 was 3,000 to 4,500 m distant, Zone 2 1,500 to 3,000 m distant, and Zone 3 was less than 1,500 m. It was estimated that with a salvo every 2 to 2.5 seconds that an aircraft traveling 275 mph (120 mps) would receive 5 or 6 shots from each RAG per zone.

Destroyers modified per Operation Barbara (increased AA weapons) were to receive up to 6 launchers while Torpedo Boats operating in the Skaggerak received many more.
