Boeing T-45 Goshawk "1988"

The McDonnell Douglas (now Boeing) T-45 Goshawk is a highly modified version of the British BAE Systems 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. The T-45 Goshawk has its origins in the mid-1970s, during which time the U.S. Navy formally commenced its search for a new jet trainer aircraft to serve as a single replacement for both its T-2 Buckeye and A-4 Skyhawk trainers.[3] During 1978, the VTXTS advanced trainer program to meet this need was formally launched by the U.S. Navy. An AngloAmerican team, comprising British aviation manufacturer British Aerospace (BAe) and American aircraft company McDonnell Douglas (MDC), decided to submit their proposal for a navalised version of BAe’s land-based Hawk trainer. Other manufacturers also submitted bids, such as a rival team of French aircraft company Dassault Aviation, German manufacturer Dornier and American aerospace company Lockheed, who offered their Alpha Jet to fulfil the requirement

Design

The T-45 Goshawk is a fully carrier-capable version of the British Aerospace Hawk Mk.60.[1][20] It was developed as a jet flight trainer for the United States Navy (USN) and United States Marine Corps (USMC). The Hawk had not originally been designed to perform carrier operations; numerous modifications were required, such as the extensive strengthening of the airframe to withstand the excessive forces imposed by the stresses involved in catapult launches and high sink-rate landings, both scenarios being routine in aircraft carrier operations.[21]

Most notable amongst the changes made to the Hawk’s design was the adoption of a comparatively simple leading-edge slat system, operated by an actuator and linkage mechanism capable of being housed within the limited free space available, along with the addition of strakes on the fuselage which improved airflow. Other modifications to the Goshawk included its reinforced airframe, the adoption of a more robust and widened landing gear, complete with a catapult tow bar attachment to the oleo strut of the new two-wheel nosegear design,[22] and an arresting hook.[23] Additionally, the wingtips were squared off, a 6-inch (0.152 m) extension to the tail fin and an increased span tailplane (which was also furnished with squared-off tips) were installed, along with a single ventral fin in front of the arrestor hook

  • T-45A
    Two-seat basic and advanced jet trainer for the US Navy and US Marine Corps
    T-45B
    Proposed land-based version which would have been basically a conventional Hawk furnished with a US Navy-spec cockpit and no carrier capability. The US Navy had wanted to procure the T-45B so that trainee pilots could benefit from an earlier training capability, but abandoned the idea during 1984 in favor of less-costly updates to the TA-4J and T-2C.
    T-45C
    Improved T-45A, outfitted with a glass cockpit, inertial navigation, and other improvements. All existing T-45As have been upgraded to the T-45C standard.[37]
    T-45D
    Tentative designation for an envisioned upgrade of the T-45, potentially incorporating various manufacturing improvements and additional equipment, such as helmet-mounted displays.[13][38]
