Selected as the basis for the airplane portion of the Navy's VTXTS jet training system, the British Aerospace Hawk is
well established as the Royal Air Force's (RAF) principal jet trainer, and has also found a similar niche with other
countries' air forces. One of several multipurpose trainer/light ground attack aircraft developed in various European
countries during the seventies, it was found adaptable to the U.S. Navy's training role, including carrier operations, with a
minimum of aerodynamic modification --a tribute to the excellent characteristics of the basic design.

The Hawk's beginnings go back to the late sixties when Hawker Siddeley (one of the predecessor companies of today's
British Aerospace) began design studies for a prospective new RAF jet trainer suitable for basic/advanced training and also
for strike/weapon delivery mission type training. The RAF settled on its final requirements in 1970 and Hawker Siddeley's
final HS-1182 design proposal was the winner of the subsequent competition. In the spring of 1972, development and a total
of 176 airplanes were ordered.

Powered by a 5,200-pound-thrust Rolls-Royce/Turbomeca Adour turbofan engine, the new trainer featured a compact,
low-wing configuration, with the instructor in a raised position behind the student, both under a large single-piece,
sideway-opening canopy, providing excellent visibility. Five external stores stations accommodate a wide variety of
weapons, including a 30mm gun pod as one of the alternates on the fuselage centerline station.

While construction was fairly conventional, every effort was devoted to improving the reliability and maintainability of
the new trainer through appropriate selection of operating system design and components and their installation.

The first Hawk made its initial flight on 21 August 1974, flying at that year's Farnborough show in early September.
Subsequent aircraft joined the flight development program which resulted in minor modifications--enlargement of the ventral
fins being one of the more obvious changes -- by the time the Hawk T.1s went into RAF training squadron service in late
1976. Assignment to the tactical weapons unit followed in 1978.

Meanwhile, one extra Hawk had been registered for company use as G-Hawk, while the Mk 50 series export Hawk
found customers in various parts of the world. Finland was the first foreign purchaser, with plans for production there.
Active NavAir interest in the Hawk as one candidate for possible replacement of T-2s and TA-4s in the Training Command
began in 1977 as part of a general study of what could be accomplished through various alternatives, including new
development as well as derivatives of the newly-developed European advanced jet trainers. In 1978, the VTXTS program
was initiated and McDonnell Douglas' Douglas Aircraft Company proposed jointly with British Aerospace a carrier-suitable
version of the Hawk as one of their approaches for the VTXTS initial 4 competition. With this proposal selected as the
winner, another British Aerospace design has found its place in Naval Aviation alongside the already well-known Harrier.

Over the next few years the T-45 Goshawk will first replace the TA-4J Skyhawk in the Advanced Jet Training Program
and then replace the T-2 Buckeye in the Intermediate Jet Pilot Training Program. The Goshawk Training System combines
academic, simulation, and flight phases into an integrated computer-based training approach that greatly improves training
efficiency and safety.
