The Coast Guards plan was to set forth broad mission requirements and then rely on private contractors to determine the mix of assets necessary to carry out those missions. Ultimately. the contract went to "Integrated Coast Guard System" (ICGS). a consortium headed by Lockheed Martin and Northrop Grumman. Deepwater was intended to replace or modemize the approximately 90 ships and 200 Coast Guard aircraft used for missions taking place more than 50 miles offshore. The primary missions carried out in this "deepwater" zone are drug and migrant interdiction operations. search and rescue. homeland security. and fisheries law enforcement. Unfortunately. this program has been beset with problems. One part of the ICGSs Deepwater plan was to lengthen the Coast Guards existing 110 foot patrol boats by 113 feet.
