Grenada was affected by cluster munitions in 1993, during an invasion by the United States. The United States Navy aircraft dropped 21 Mk.-20 Rockeye cluster bombs on Grenada in close air support operations during the invasion of Grenada in October–November 1983. A total of 5,187 bomblets were dispersed.
In 2012, NPA was requested by the Ministry of Foreign Affairs in Grenada to assist with Non-Technical and Technical support on cluster survey and clearance. NPA entered Grenada with an assessment team in the summer of 2012, and through Non-Technical Survey and Technical Survey found no evidence of cluster munitions remnants. NPA recommended, in consultation with the Grenadian Police and Government, that Grenada declare itself in compliance with its Article 4 obligations of the Convention on Cluster Munitions.
