McDonnell Douglas T-45 Goshawk

The T-45 Goshawk is a highly modified version of the BAE Hawk land-based training jet aircraft. Manufactured by McDonnell Douglas (now Boeing) and British Aerospace (now BAE Systems), the T-45 is used by the United States Navy as an aircraft carrier-capable trainer.

Design and development

The T-45 Goshawk is a fully carrier-capable version of the Hawk Mk.60.[1][3] It was developed for the United States Navy (USN) for use in training.

The Goshawk's origins began in the mid-1970s, when the US Navy began looking for replacement for its T-2 and TA-4 trainers.[4][5] The US Navy started the VTXTS advanced trainer program in 1978. British Aerospace and McDonnell Douglas proposed a version of the Hawk and were awarded the T-45 contract in 1981.[6]

The Hawk had not been designed for carrier operations. Numerous modifications were required for Navy carrier use, including improvements to the low-speed handling characteristics and a reduction in the approach speed.[4] Other changes were strengthened airframe,[7] more robust and wider landing gear with catapult attachment and an arresting hook.[4] It features a two-wheel nose landing gear.[8]

The Goshawk first flew in 1988 and became operational in 1991.[8] BAE Systems manufactures the fuselage aft of the cockpit, the air inlets, the vertical stabilizer of the T-45 at Samlesbury, and the wings at Brough, England. Boeing manufactures the remainder of the aircraft and assembles them in St. Louis, Missouri.

On 16 March 2007 the 200th airframe was delivered to the US Navy. Their requirements call for 223 aircraft, and the T-45 service is slated to continue until at least 2035.[9]

The T-45 has been used for intermediate and advanced portions of the Navy/Marine Corps strike pilot training program with Training Air Wing ONE at Naval Air Station Meridian, Mississippi and Training Air Wing TWO at Naval Air Station Kingsville, Texas. The T-45 replaced the T-2C Buckeye trainer and the TA-4J Skyhawk II trainer with an integrated training system that includes the T-45 Goshawk aircraft, operational and instrument flight simulators (OFT/IFT), academics, and training integration system support. In 2008, the T-45 began operation in the advanced portion of Navy/Marine Corps Naval Flight Officer (NFO) training with Training Air Wing SIX at Naval Air Station Pensacola, Florida.

The T-45's A and C models are currently in operational use. The T-45A, which became operational in 1991, contains an analog cockpit design while the newer T-45C, which was first delivered in December 1997, features a new digital "glass cockpit" design. All T-45A aircraft will eventually be converted to a T-45C configuration under the T-45 Required Avionics Modernization Program (T-45 RAMP).
[edit] Variants

T-45A
Two-seat basic and advanced jet trainer for the US Navy.

T-45B
Proposed land-based version for the US Navy, which would have been basically a conventional Hawk with a USN cockpit and no carrier capability. The USN had wanted the T-45B to get an earlier training capability, but abandoned the idea in 1984 in favor of less-costly updates to the TA-4 and T-2.

T-45C
Improved T-45A with glass cockpit, inertial navigation, and other improvements. Existing T-45As are being upgraded to the T-45C standard.
