- RPG (Computing/Electronics) RPG (Report Program Generator) is a high-level programming language that is mainly applicable to commercial data-processing applications. This language was a derivative of the FARGO programming language for the IBM 1401 introduced in 1959, both languages were designed to make it easier for people used to programming electromechanical Unit Record (punchcard) data processing equipment with plugboards to be comfortable programming electronic digital computers. It has gone through many revisions since then and is now available on all business computers.
- The RPG is the computer in the NEXRAD system that receives polar-coordinate base radar data from the RDA and processes these data into end-user products. Algorithms are utilized for pattern-recognition, rainfall estimation, computation of VIL and other products. The RPG communicates these products to end-users. A specific subset of available products is always generated for the NIDS vendors for distribution outside of the NWS, DoD, and FAA. ...

- RPG (military equipment) In military equipment an RPG is a "rocket propelled grenade". The letters come from the Russian transliteration "ruchnoy protivotankovyy granatomyot". The RPG consists of a system which contains 4 components, the shaped explosive charge, the metal cone inside lining of the shaped explosive charge, the propulsion system, and the stabilization system. Upon impact the shaped explosive charge detonates which crushes and melts the metal cone lining transforming it to a rod shaped jet of molten metal that can kinetically penetrate through about 8 inches of normal steel, once inside the vehicle/building the molten metal sprays everywhere causing fires, killing in a manner not much different than a shotgun (except the "pellets" are molten instead of solid), detonating explosives, etc. This is why this easy, cheap, weapon has taken more lives than any other antivehicle hand held weapon system in history. The propulsion system speaks for itself, and the stabilization fins unfold immediately after being shot keeping the projectile on the same vector of motion (as much as possible).
