The Arthuristan Dynamics Mercury is a long range strike aircraft of Arthuristan origin. Originally introduced in the early-60's, it was originally designed to provide the Fleet Air Arm and Commonwealth Air Force with low-level 'below the radar' attack capability. Owing to the requirements of low-altitude flight, the Mercury possesses a very durable airframe resistant to metal fatigue, and possesses very stable low-level characteristics. Despite the fact that it is incapable of supersonic flight, at below 150m it is faster than most aircraft with a theoretical top speed of mach 2.

The Mercury S.3 configuration, following a mid-70's upgrade package, became the definitive variant of the Mercury strike aircraft. It features a terrain-following radar for night- and all weather low-altitude operations, 'bulging' bomb bay doors to accommodate additional fuel, as well as compatibility with up to four ACM-2 Renove anti-ship missile.

The Mercury has been largely replaced by multirole models such as the Arthuristan Dynamics Fury and, later, the UFC Tempest. However, the Mercury ECR electronic warfare aircraft remains in service in limited numbers.

Mercury ECR

The Mercury ECR is an electronic warfare variant of the Mercury, specifically designed to carry out SEAD missions, or to support strike packages by protecting friendly aircraft against enemy SAM's. It is equipped with six Belfrasian ALQ-99 tac-jammer units in the bomb bay, with their multi-function (omnidirectional and directional) antennae projecting out in a canoe-shaped structure between the forward undercarriage and the bomb bay. An ALQ-41 jammer is also carried for self-defence jamming. The Mark-7V Radar Warning Receiver is mounted as a bulb atop the vertical stabiliser. This unit is responsible for detecting and prioritising threat radars for power-managed jamming by the ALQ-99 or ALQ-41 units. It also has a secondary function in providing targeting information to any anti-radiation missiles the aircraft may carry on its external pylons.

While strike variant Mercuries have been retired, the -ECR has not been retired and is sustained in service by spare parts liberated from scrapped strike aircraft. They will likely remain until sufficient numbers of UFC F-29 Hurricane are available to take over its specialist electronic warfare and defence-suppression functions.
