We’ve talked numerous times about the Guided MLRS, the Excalibur 155mm artillery round, guided mortar rounds and recently the HVP. Having cracked the code on how to design a guidance system for artillery ammunition, we’re going to see a growing range of projectiles with precision capability for an expanding set of guns.
Here’s BAE System’s self funded project, the Multi-Service Standard Guided Projectile, or MS SGP. It’s an adaptation of the Long Range Land Attack Projectile (LRLAP) designed for the 155mm Advanced Gun System (AGS) for the DDG-1000 Zumwalt class destroyers.
The MS SGP is being designed specifically for the US Navy’s current standard 5” gun, the Mk45 Mod 4. BAE systems, noting that 155mm is larger than 5” (127mm) has proposed using the MS SGP in a saboted configuration from Marine and Army 155mm guns.
To date, there’s been a successful guided shot, but no production contracts.
