Hawker 800

The Hawker 800 series originated from a British Aerospace (BAe) initiative launched in April 1981 to develop an improved version of the BAe 125-700. This effort resulted in the BAe 125-800, which completed its first test flight in May 1983. The aircraft incorporated several enhancements over the 125-700, including a redesigned cockpit windscreen, a modified rear fuselage fairing, and the adoption of a glass cockpit. Engine power was increased with uprated Garrett TFE731-5R-1H engines, providing 4,300 lb of thrust compared to the previous 3,700 lb. Aerodynamic efficiency was also improved through new outer wing sections designed to reduce drag. The 125-800 proved commercially successful, with the 200th aircraft of the 800 series delivered within five years of the initial BAe 125 flight in August 1961. In 1994, Raytheon acquired BAe Corporate Jets, renaming it Raytheon Aircraft. This entity was subsequently divested and became Hawker Beechcraft Corp. in March 2007. The Hawker 850XP, certified in March 2006, introduced winglets, which extended its operating range by 100 nautical miles (190 km), along with upgraded avionics and a redesigned interior. The standard Hawker 800 has a maximum payload capacity of 2,000 lb (907 kg).

Design

While primarily a civilian platform, the Hawker 800 series has been adapted for military applications. These specialized military variants can feature enhanced observation windows, a flare and marker-buoy dispenser system, a life-raft and emergency equipment dropping system, and enhanced salt water corrosion prevention for maritime operations.

Operational History

The Japan Air Self-Defense Force operates the U-125A, a variant specifically modified for maritime search and rescue. This version includes the large observation windows, dispenser systems, and enhanced corrosion prevention, augmented by a Toshiba 360-degree search radar, Melco thermal imaging equipment, and military communications systems. The Republic of Korea Air Force employs the RC-800, a modified Hawker 800XP, for tactical aerial reconnaissance, surveillance, and Signals Intelligence (SIGINT) missions. Beyond these specialized roles, the aircraft is operated by the Air Forces and Navies of Nigeria, Pakistan, and the Philippines.
