The Lynx project was a plan to develop new multi-functional helicopters to replace the old helicopters operated by the English army in the late 1950s, and 3 English airplane manufacturers worked together to develop this helicopter.
The development of this helicopter continued through the mid 70s, adding more advanced navigation systems such as the automatic navigation system. It was named the Lynx after the performance evaluation flight in June 1972, and was deployed by the English army starting at the end of 1977.

For the Navy Lynx, the landing gear was changed to three-wheel landing gear, and is equipped with weapons and electronic flight equipment adequate for anti-submarine and anti-vessel operations.
In addition, a detection and tracing radar was equipped on the nose of the craft, the wings of the rotor were designed to be folded, and the craft was armed with anti-vessel missiles, torpedoes, mines and it was also equipped with an underwater sound wave detector, a rescue winch, and an auto-pilot system.

The Lynx 3, which flew for the first time in June 1984, had an improved composite tail rotor, a body that was 30 cm wider to increase the passenger quarter capacity, and its weight was increased by 27%.
In order to minimize storage space on a ship, the Navy Lynx 3 was designed so that the main and tail rotors could be folded, an omni-directional 360-degree detection radar was equipped on the nose, and the craft was also equipped with underwater soundwave detectors and active or passive soundwave detection buoys.

As for anti-submarine and anti-shipl weapons, it is armed with torpedoes and mines or anti-vessel missiles
