The guided missile frigate USS Curts is due back at Naval Station San Diego Wednesday after four months at sea. The ship has been deployed in support of Cooperation Afloat Readiness and Training, or CARAT. CARAT is an annual series of bilateral military exercises between the United States and various countries in Southeast Asia, including Thailand, Brunei, Singapore and Malaysia. The exercise phases focused on training with the participating nations' sea services to improve military readiness. During the deployment, the ship also went to Chennai, India, to participate in the South Asia Search and Rescue Exercise, or SAREX, a multinational exercise partially designed to train participants in regional nighttime search and rescue procedures. Participating forces and observers came from India, Sri Lanka, Madagascar and elsewhere. The Curts returns to Naval Station San Diego at 10:00 a.m.
