The 76 mm L23A1 gun is a British low-velocity rifled tank gun developed by Royal Ordnance for the FV101 Scorpion and related CVR(T) fire-support vehicles. It was designed as a lighter derivative of the L5A1 with interchangeable fixed ammunition, hydropneumatic recoil, and a practical rate of fire of six rounds per minute, then saw British operational use on Scorpion vehicles in the 1982 Falklands War and 1990 Gulf War.
British Scorpion vehicles fitted with the L23A1 family gun provided direct fire support during the 1982 Falklands campaign, including actions around Wireless Ridge and Mount Tumbledown.
During Operation Granby, British Scorpion units using the 76 mm L23A1 gun served forward of main armored formations and with RAF Regiment Scorpion/Spartan groupings.
Role detailsThe L23A1 was designed around the compact Scorpion turret and remained closely tied to CVR(T) fire-support service.

The L23A1 was developed to stay compatible with fixed 76 mm ammunition in the Scorpion family, and later catalogs list several 76 mm natures for the L23/L23A1 gun set.
| Ammunition | Ammunition type | Firing evidence |

 | 76 mm canister round | Nexter lists M333 canister ammunition for the FV101 Scorpion's L23 and L23A1 guns. Sources: Nexter 2016 Catalog |
 | 76 mm high-explosive tracer round | Nexter lists the M330 HE-T round as part of the 76 mm ammunition set compatible with the Scorpion L23/L23A1 gun family. Sources: Nexter 2016 Catalog |
| 76 mm HEP-T / HESH-T projectile | Chemring and Nexter list M329 for the L23/23A1 gun family, and Think Defence describes the L23A1 as a lighter derivative of the L5A1 with preserved ammunition interchangeability. Sources: Chemring Munitions Catalog, Nexter 2016 Catalog, Think Defence |
| 76 mm training round | Nexter lists the M331 training round for use with the FV101 Scorpion's L23 and L23A1 guns. Sources: Nexter 2016 Catalog |

The L23A1 page is most useful when read as a Scorpion fire-support component: sources connect the gun to the CVR(T) turret, its fixed 76 mm ammunition family, and British operational use through the vehicle.
| Area | Sourced detail | Reader context |
|---|---|---|
| Gun family | Think Defence describes the L23A1 as a Royal Ordnance lightened derivative of the L5A1 that preserved ammunition interchangeability. | This explains why L5/L23-family 76 mm rounds appear across Saladin and Scorpion ammunition references. |
| Vehicle fit | Army Guide and Think Defence identify the L23A1 with FV101 Scorpion and related CVR(T) fire-support vehicles. | The gun is cataloged as a weapon because it shaped the Scorpion's direct-fire role, not as a separate towed artillery piece. |
| Ammunition set | Nexter lists canister, HE-T, HEP-T, training, blank, and smoke rounds for the L23/L23A1 Scorpion gun family. | The ammunition links separate reusable munition records from the gun's own background page. |
The L23A1 emerged from the British CVR(T) program as a lighter 76 mm gun for Scorpion-class reconnaissance and fire-support vehicles.
Think Defence cites a March 1970 House of Commons Army Estimates debate noting the Scorpion and its 76 mm gun in the final phase of development.
British Scorpion vehicles armed with the L23A1 family gun supported land fighting during the Falklands campaign.
British Scorpion units used the 76 mm gun in reconnaissance and security roles during the 1990 Gulf War.
Think Defence reports roughly 2,000 gun and turret units produced by January 1993.
The 76 mm Scorpion was withdrawn from front-line British Army service around 1994, with some vehicles retained for reserve or training roles.
