the Federation armada of dreadnought space warships. Realizing that the gap needed to be closed, the Federation instituted Project V (short for "Project Victory"), a development program that would produce a counterpart Federation mobile suit design, with the capability for mass-production a mandatory requirement. While the ultimate result of the program was the mass-produced RGM-79 GM series, the high-performance RX-78 series prototypes served as the main testbed for the Project V engineers to trial several new design concepts that proved profoundly influential for the coming decades. Some of the developments in the RX-78 models were later incorporated into the GM line, but many were scrapped due to cost and/or complexity. Only eight RX-78 suits were produced during the One Year War, although continual remodelling and upgrading created the impression that there were more than eight units. Although the RX-78 suits are designated RX-78-1 to RX-78-8, the final digit indicated the design version of the unit, rather than its actual number. In addition, the Earth Federation Forces started a G-4 project which consist of four RX-78s for each of its branches, and EFSF (Earth Federation Space Force) used information of the RX-78-4 to develop the RX-78NT-1. According to the director's production notes of Mobile Suit Gundam 0080: War in the Pocket, it could be considered to be the 9th unit of RX-78, initially intended to be used by Amuro Ray. Although what unit the EFAF (EF Air Force) developed is not specifically mentioned, in the semi-canon manga Mobile Suit Gundam: MS Generation the EFAF created the RX-78E (GT FOUR/Gundam Transformer/Flight & Operations Unifications Reactors), which is different from the eight RX-78s produced. Another unit is the EFGF's (EF Ground Force) RX-78XX, which uses scrap parts of the RX-78s, just like the RX-79[G] Gundam Ground Combat Type. The EFN (EF Navy) developed the RAG-79-G1 as the G-4 project's marine type Gundam, yet it is only an upgrade of the RAG-79 Aqua GM for Ace pilots with just the head and generator changed. After the One Year War, the GP series are numbered after the RX-78 convention, despite being newly produced units. The variation among the Gundams was originally indicated by differences in colouration, indicating upgrades to completely internal equipment and technology, although later variants displayed externally visible upgrades. For example, Unit 4 and Unit 5, which exist mainly in games and as model kits, provide additional mounting points and weaponry. The RX-78
