The Caiman completed testing by the U.S. military at the Aberdeen Proving Grounds in July 2007. On July 13, 2007, Armor Holdings received a prime contract award by the U.S. Navy on the behalf of the U.S. Marine Corps for $518.5 million under the MRAP vehicle program. The contract specified delivery of 1,154 Category I MRAP vehicles and 16 Category II MRAP vehicles by the end of February 2008.[2]
BAE Systems acquired Armor Holdings in 2007 and continued production of the Caiman.
In August 2009, the U.S. Army announced that Oshkosh Defense had been awarded the FMTV A1P2 rebuy production contract. This award did not include the Caiman.
In September 2010 BAE Systems was awarded a $629 million contract from the U.S. MRAP Joint Program Office to upgrade 1,700 Caiman MRAP vehicles to Caiman Multi-Terrain Vehicle - Caiman MTV standard. The upgraded vehicle integrates a refurbished and improved armored capsule from an existing vehicle with a new high-power automotive power train, chassis and independent suspension made by ArvinMeritor.[3] Greater survivability is achieved through an enhanced monolithic floor, a strengthened chassis frame and better blast absorbing seats.[4]
On December 18, 2011, a Caiman was part of the last U.S. military convoy out of Iraq, being the last vehicle to cross the border into Kuwait, signifying the end of U.S. military presence and operations in the eight-year Iraq War.
Starting in October 2013, local police and sheriff offices in the U.S. began to acquire Caiman 6x6 MTVs. The U.S. government offered these vehicles to local law enforcement as the need for them greatly decreased after the Iraq and Afghanistan wars ended. The Caiman MTV normally costs $412,000, but is sold for only its transportation costs to the local jurisdiction.[5][6]
In September 2014, the U.S. approved a $2.5 billion deal with the United Arab Emirates Army for over 4,500 surplus U.S. MRAPs for increased force protection, conducting humanitarian assistance operations, and protecting vital international commercial trade routes and critical infrastructure. 1,150 vehicles were Caimans.[7]
