Northrop Grumman has signed contracts to continue the production of Precision Guidance Kits (PGK) for 155mm artillery projectiles.

The $137m modification contract is for additional PGKs for the US Army and US Marine Corps (USMC).

The company has also achieved a milestone with the production and delivery of 50,000 artillery kits.

With a combined guidance capability functioning in one device, the PGK transforms 155mm artillery projectiles by combining fuse functions and GPS guidance into one device that fits into standard fuse wells.

This helps to reduce the number of artillery projectiles required to attack targets and lower collateral damage while delivering accuracy.

Recently, the company expanded its PGK production capacity in Plymouth, Minnesota, US.

The additional capacity will increase the daily, single shift production rate by 15% to meet the demand.

Northrop Grumman armament systems vice-president Dan Olson said: “PGK is an example of how we are able to apply new capabilities to improve existing weapons and systems.

“Beyond our existing PGK production, we are developing additional technologies that will add precision to future long-range artillery requirements.”

Last month, Northrop Grumman and Raytheon Missiles & Defense have partnered to bid for the US Missile Defense Agency (MDA) Next Generation Interceptor (NGI) contract.

The US Department of Defense issued a request for proposal (RFP) for the NGI on 24 April this year.
