In 1963 NATO agreed a NATO Basic Military Requirement 39 for close support artillery, either towed or tracked. Subsequently Germany and UK started discussions and design studies and in 1968 established agreed operational characteristics for a towed 155 mm close support gun. Italy became a party to the agreement in 1970.

Key requirements were:

  • a detachable auxiliary power unit (APU)
  • an unassisted range of 24 km and 30 km assisted
  • a burst capability of 3 rounds in 15–20 seconds, 6 rounds per minute for a short period and 2 rounds per minute sustained
  • be able to fire all 155 mm munitions in NATO service, plus a new range of ammunition.

The two national authorities had overall responsibility for R&D, and Vickers Ltd was the co-ordinating design authority. They were also the design authority for the carriage and Rheinmetall GmbH was the authority for the elevating mass, including the sights, and for the APU. There was a further breakdown at a more detailed level and production worksharing. The UK Royal Armament Research and Development Establishment (RARDE) was responsible for designing the HE projectile and the charge system. Germany was responsible for Smoke, Illuminating, Minelet and extended range HE, although development of the last two was not completed in the program.

The intention was for FH70 to replace the M114 155 mm howitzer and equip general support battalions in German divisional artillery regiments and to equip three (two Territorial Army (TA)) British general support medium regiments replacing the 5.5-inch gun. In the event, it actually equipped UK regular regiments in direct support of infantry brigades until after the end of the Cold War, and only replaced the L118 light gun in two TA regiments, 100th (Yeomanry) Regiment Royal Artillery and 101st (Northumbrian) Regiment Royal Artillery (Volunteers) from 1992 to 1999.
