Scenes from the 2023 Jefferson Lab Run-A-Round held at the Newport News campus on Wednesday, May 18, 2023. (Photo by Aileen Devlin | Jefferson Lab)
The FH70 (Field Howitzer for the 1970's) is a Towed Howitzer in use with several nations, in 1963, NATO agreed a NATO Basic Military Requirement 39 for Close Support Artillery, either Towed or Tracked. Subsequently, Germany and the UK started discussions and design studies and in 1968 established agreed operational characteristics for a Towed 155 mm Close Support Gun and 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 to 20 secondsnds, 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 researchanddevelopment, 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 155mm 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 5.5in 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.
FH70 Howitzer had several interesting features, including :-
> a vertical sliding-block breech that provided obturation and held a primer magazine containing
12 primers (a similar breech was fitted to German M109G)
> burst fire
> an on-board 1700cc Volkswagen engine to power the hydraulics and to assist bringing the gun
into and out of action (with hand pump back-up) and to move the gun up to 20km at low speed
without towing by an artillery tractor
> electronic firing data display taking data from the otherwise conventional azimuth and elevation sights.
The Barrel was 39 calibres long, giving 827m/s Standard Maximum Muzzle Velocity, it had a Muzzle Brake giving 32% efficiency. Other conventional features included a Split Trail and Turntable Sole Plate. Initially, it had assisted loading, but became an early user of Flick-Ramming. In accordance with long-standing UK practice, it used one-man laying. All this meant that the Gun could be operated by a minimum detachment of only 4 men (Commander, Layer and 2 Loaders) The Burst Fire Rate was 3 rounds in 15sec, it was also fitted with a Direct Fire Telescope.
There were a number of design flaws that became apparent in service, the equipment entered full operational service in the UK in 1980. It became clear that there were significant difficulties with the Tube Feed System in anything but ideal conditions. 1st Regiment RHA, a Unit that had conducted the Troop Trials, developed their own procedures to solve these problems, related to dust contamination, and this process became established in Official Manuals in due course. More significantly, the trails of the Gun proved to be weak at the point where maximum stress was incurred when the equipment was towed, this resulted in modification work on the UK Guns in 1987. There were continual problems with the Drive Train on the Flat-4 VW APU, and the Hydraulic System was always vulnerable to the obvious problems posed by external, Non Armoured, housing in Combat Conditions, in addition, the complex Dial Sight Carrier was vulnerable to damage.
The new Projectiles conformed to the Quadrilateral Ballistics Agreement between US, UK, Germany and Italy, in essence, this meant a Shell with the same shape and dimensions as the US M549 Rocket-Assisted Projectile. The Standard High Explosive (HE) Shell (UK designation L15) is a thin wall design weighing 43.5kg and containing 11.3kg of HE, this remains the largest HE load for a Standard 155mm Shell. The Propellant System comprises three different Bagged Cartridges with Triple-Base Propellant. Cartridge 1 gives Charges 1 & 2, Cartridge 2 give Charges 3–7 and Cartridge 3 is Charge 8, which gives a maximum range under standard conditions of 24.7km.
Each nation developed its own Fuzes and Ammunition Packaging, in the UK's case, this led to the Unit Load Container carrying 17 complete Rounds, including Shells with Fuzes fitted, a novelty for 155mm. Standard US Pattern 155mm Ammunition can also be fired, although US Primers proved problematic for the Primer Magazine and Feed due to their variation in size.

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 155mm 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 5.5in 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.
FH70 Howitzer had several interesting features, including :-
> a vertical sliding-block breech that provided obturation and held a primer magazine containing
12 primers (a similar breech was fitted to German M109G)
> burst fire
> an on-board 1700cc Volkswagen engine to power the hydraulics and to assist bringing the gun
into and out of action (with hand pump back-up) and to move the gun up to 20km at low speed
without towing by an artillery tractor
> electronic firing data display taking data from the otherwise conventional azimuth and elevation sights.
The Barrel was 39 calibres long, giving 827m/s Standard Maximum Muzzle Velocity, it had a Muzzle Brake giving 32% efficiency. Other conventional features included a Split Trail and Turntable Sole Plate. Initially, it had assisted loading, but became an early user of Flick-Ramming. In accordance with long-standing UK practice, it used one-man laying. All this meant that the Gun could be operated by a minimum detachment of only 4 men (Commander, Layer and 2 Loaders) The Burst Fire Rate was 3 rounds in 15sec, it was also fitted with a Direct Fire Telescope.
There were a number of design flaws that became apparent in service, the equipment entered full operational service in the UK in 1980. It became clear that there were significant difficulties with the Tube Feed System in anything but ideal conditions. 1st Regiment RHA, a Unit that had conducted the Troop Trials, developed their own procedures to solve these problems, related to dust contamination, and this process became established in Official Manuals in due course. More significantly, the trails of the Gun proved to be weak at the point where maximum stress was incurred when the equipment was towed, this resulted in modification work on the UK Guns in 1987. There were continual problems with the Drive Train on the Flat-4 VW APU, and the Hydraulic System was always vulnerable to the obvious problems posed by external, Non Armoured, housing in Combat Conditions, in addition, the complex Dial Sight Carrier was vulnerable to damage.
The new Projectiles conformed to the Quadrilateral Ballistics Agreement between US, UK, Germany and Italy, in essence, this meant a Shell with the same shape and dimensions as the US M549 Rocket-Assisted Projectile. The Standard High Explosive (HE) Shell (UK designation L15) is a thin wall design weighing 43.5kg and containing 11.3kg of HE, this remains the largest HE load for a Standard 155mm Shell. The Propellant System comprises three different Bagged Cartridges with Triple-Base Propellant. Cartridge 1 gives Charges 1 & 2, Cartridge 2 give Charges 3–7 and Cartridge 3 is Charge 8, which gives a maximum range under standard conditions of 24.7km.
Each nation developed its own Fuzes and Ammunition Packaging, in the UK's case, this led to the Unit Load Container carrying 17 complete Rounds, including Shells with Fuzes fitted, a novelty for 155mm. Standard US Pattern 155mm Ammunition can also be fired, although US Primers proved problematic for the Primer Magazine and Feed due to their variation in size.
The FH70 (Field Howitzer for the 1970's) is a Towed Howitzer in use with several nations, in 1963, NATO agreed a NATO Basic Military Requirement 39 for Close Support Artillery, either Towed or Tracked. Subsequently, Germany and the UK started discussions and design studies and in 1968 established agreed operational characteristics for a Towed 155 mm Close Support Gun and 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 to 20 secondsnds, 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.
