OK people. I think I can see where the design is coming from.
https://en.wikipedia.org/wiki/BAE_Systems_Hawk#Design
The Hawk is an advanced trainer with a two-man tandem cockpit, a low-mounted cantilever wing and is powered by a single
turbofan engine. Unlike many of the previous trainers in RAF service, the Hawk was specifically designed for training.
[5] Hawker had developed the aircraft to have a high level of servicability, as well as lower purchasing and operating costs than previous trainers like the
Jet Provost.
[24] The Hawk has been praised by pilots for its agility, in particular its roll and turn handling.
[25]
The design of the fuselage included a height differential between the two seats of the cockpit; this provided generous levels of visibility for the instructor in the rear seat.
[26] Each cockpit is fitted with a
Martin-Baker Mk 10B zero-zero rocket-assisted
ejection seat.
[26] Air is fed to the aircraft's rear-mounted
Rolls-Royce Turbomeca Adour engine via intakes on each of the forward
wing roots. During the aircraft's development, Hawker had worked closely with Rolls-Royce to reduce the engine's fuel consumption and to ensure a high level of reliability.
[24]
Even within the development stages, a Hawk variant was intended to also serve as a single-seat ground-attack fighter; both the trainer and fighter models were developed with the export market in mind.
[5] On single seat models, the forward cockpit area which normally houses a pilot is replaced by an electronics bay for avionics and onboard systems, including a fire control computer, multi-mode radar, laser rangefinder and
forward-looking infrared (FLIR).
[27] Some export customers, such as Malaysia, have extensive modifications to their aircraft, including the addition of wingtip hardpoint stations and a fittable inflight refuelling probe.
[28]
The Hawk was designed to be manoeuvrable and can reach
Mach 0.88 in level flight and Mach 1.15 in a dive, thus allowing trainees to experience
transonic flight before advancing to a
supersonic trainer.
[29][30] The airframe is very durable and strong, stressed for +9
g, the normal limit in RAF service is +7.5/-4 g.
[31] A dual hydraulic system supplies power to operate systems such as the aircraft's flaps, airbrakes and landing gear, together with the flight controls. A
ram air turbine is fitted in front of the single tail fin to provide backup hydraulic power for the flight controls in the event of an engine failure,
[32] additionally a
gas turbine auxiliary power unit is housed directly above the engine.
The Hawk is designed to carry a centreline gun pod, such as the 30 mm
ADEN cannon, two under-wing pylons, and up to four
hardpoints for fitting armaments and equipment.
[5] In RAF service, Hawks have been equipped to operate the
Sidewinder air-to-air missiles. In the early 1990s, British Aerospace investigated the possibility of arming the Hawk with the
Sea Eagle anti-ship missile for export customers.
[33] In 2016, BAE Systems was studying the development of a so-called 'Combat Hawk', potentially equipping it with a new slotted wing, additional sensors and weapons, a
head-mounted display, and a single large-screen display in the forward cockpit.
