The Mikasa Gallienus MiK-58 (NATA reporting name: Fishhook) is a lightweight fighter-bomber originally developed by Elatia in the late-1950's based on the Suvarovan MiG-21. It was Elatia's first fighter capable of attaining Mach 2 speed in level flight. This simple fighter was produced in very large quantities and until the late-1970's formed the backbone of the Elatian Air Force. Its international counterparts include the Messidorian Mirage III, the Arthuristan Greenwich Super Tigress, the Ghantish E-35 Draco and the Mutulese K'akmul 5.

Design

The MiK-58's designers were impressed by the Fishbed's high power-to-weight ratio. However, they were not minded to adopt the delta-wing of the latter, which conferred significant acceleration and climb rates, but at the cost of turning ability as well as take-off length. What Elatia needed was not so much a dedicated interceptor, but an all-purpose fighter. Accordingly, Elatian designers decided to use the more mature technology of swept-back wings in order to improve the aircraft's prowess in a traditional dogfight, which in the era before reliable radar-guided beyond-visual-range missiles remained the primary form of air-to-air combat.

The MiK-58's most advanced feature was its turbojet engine which, aside from its normal reheat function, had a second fuel pump to allow for the use of an 'Enhanced Power Rating' (EPR) mode. The latter, which could only be sustained for two minutes, produced up to 97.5kn of thrust and allowed the MiK-58 to attain a power-to-weight ratio of nearly 1:1, an impressive achievement for its time. Its disadvantages included the primitive ranging radar mounted within the small shock cone (which was incapable of being used to direct radar-guided missiles), small payload and in particular its limited combat endurance. Despite periodic upgrades in both internal and drop tank fuel capacity, the MiK-58's role throughout its service life remained primarily that a short-range fighter optimised for providing local tactical air cover over the battlespace, highly reliant upon Ground-Controlled Interception ('GCI').

In the air-to-air role, the early model MiK-58 was usually equipped with two short-range heat-seeking missiles, plus three drop tanks. It was also designed from the outset with a secondary ground-attack capability, carrying bombs between 250-500kg in weight as well as rocket pods.

Modernisation

The Elatian Air Force had intended to replace the MiK-58 with the Mikasa Gallienus MiK-70 Visko and other models. However, for a variety of reasons this has not happened and in fact the MiK-58 has remained in service after the retirement of the fighter variants of the MiK-70.

The latest version is the MiK-58M2, which inccorporates a new pulse-doppler radar that allows the fighter to track eight targets at beyond visual range and engage two with radar-guided missiles. It is also equipped with tactical data-link and two multi-function displays to create a partial-glass cockpit, radar-warning receiver, a dual-screen HUD, helmet-mounted display to enable the use off modern high off-boresight heatseeking short-range misiles, as well as an optional targeting pod for the use of precision-guided ground attack munitions and wing-tip dispensers for chaff and flare. Ejector rails increase the number of heatseekers it can carry to four in addition to external fuel.

A simpler upgrade, the MiK-58M1, omits the new radar and is primarily intended as a strike aircraft with secondary air-to-air capabilities.
