Background

PAAMS was originally intended to be deployed in the 'Common New Generation Frigate' (also known as the ) for the navies of the United Kingdom, France, and Italy.
The French
DGA placed a contract with EUROPAAMS on 11 August 1999 for the development and initial production of the PAAMS warfare system along with the associated Long Range Radar (LRR) system. The contract included one PAAMS system and one LRR for each of the first British, French, and Italian new class of warships. Irreconcilable differences in the design requirements and workshare disagreements led to the United Kingdom leaving the 'Common New Generation Frigate' project in October 1999. After withdrawing, Britain instead decided to pursue a national warship design, designated the

Testing
*During its first major warfare sea exercise aboard , the ship's Combat Management System crashed while under simulated air attack due to a power failure, and the ship lost use of its combat management system; the ship's crew reverted to use of binoculars to spot incoming airborne threats until the CMS had been restarted.
*In 2009, two test firings of PAAMS in the British configuration from the Longbow trials barge failed due to "failures in the terminal phase of the engagement." It was believed that "production weaknesses" in a batch of Aster 30 missiles imported from France were to blame.
