The squadron flies the KC-135R Stratotanker, which provides the core aerial-refueling capability for the Air Force and has excelled in this role for more than 50 years. This unique asset enhances the Air Force's capability to accomplish its primary missions of Global Reach and Global Power. It also provides aerial-refueling support to Air Force, Navy and Marine Corps and allied-nation aircraft. The KC-135 is also capable of transporting litter and ambulatory patients using patient support pallets during aeromedical evacuations.
Established in 1993 to provide the Hawaii Air National Guard an air refueling mission and to establish an air refueling capability over the middle Pacific Ocean. It began as a small 4 aircraft squadron until 1995 when it was authorized to grow to 8 aircraft and increased personnel.
From late February to April 1998, four KC-135R aircraft from the 203d, and over 200 154th Wing maintenance and support guard members deployed to Istres Air Base, France, to participate in Operation Deliberate Forge. As real world hostilities began, the focus turned to Operation Allied Force. Seventy combat sorties were flown with a 100 percent mission success rate and zero ground/air mishaps or injuries, and over 3.9 million pounds of fuel were transferred to U.S. and NATO aircraft.
When political and military tensions built up in Southwest Asia, a KC-135R and guard members from the Squadron and 154th Logistics Group were deployed to Eielson Air Force Base, Alaska, to support Operation Phoenix Scorpion in November 1998. The unit took part in exercise RIMPAC 2000, taking place in June 2000.
In February 2001, a KC-135 Stratotanker aircraft from the squadron provided assistance to the U.S. Department of Defense humanitarian aid airlift to earthquake stricken India. A 203d KC-135 tanker took off from Hickam Air Force Base to refuel the first India-bound C-5 Galaxy cargo aircraft laden with relief supplies. The U.S. Air Force C-5 aircraft had departed Travis AFB, California, loaded with heavy equipment and other relief supplies needed in the disaster areas.
On 4 February 2003, two squadron KC-135R Stratotankers from the squadron re-fueled two Air Combat Command B-1B Lancers over the Pacific Ocean while the bombers finished up an 19-hour, more than 15,000 mile, global power mission.
