The original Quixote Class frigate was slow, poorly armed and armoured. Back in the early 28th century, the SLDF began converting mothballed Quixotes and using them as transports. In doing so, they created a new class of vessel - the Volga Class cargo hauler.

However, there were quite a few more Quixotes, lying idle in shipyards across the Inner Sphere...particularly those operated by Comstar - famous for their love of technology, old or new.

When the small band of Terran citizens fled their homeworld after Word of Blake took control of the planet, they took with them a small fleet of ships, most of them antiquated designs that had not seen active service for a over a century. One of these just happened to be an old Quixote.

After establishing a new colony in the Periphery, the people of the newly-christened Britannic Coalition set about defending themselves from the bands of pirates that operate with relative impunity on the margins of the Inner Sphere.

The Type 60 is almost unrecognisable from the sorry-looking vessel that had to be towed from Terra behind a Monsoon Class battleship.

Although the hull and superstructure are broadly similar, they have been greatly reinforced and now bristle with weaponry. Essentially, the ship has undergone a "Pimp My Ride" style transformation.

By doing away with the enormous cargo spaces of the original design and by reducing the huge ammo payloads carried by its Class 10 NACs, over 100,000 tons were made available to turn   it from a huge, sitting duck, into a real predator.

The drive has been upgraded to give the Type 60 a sustainable acceleration of 2Gs. Structural integrity has been tripled and armour protection increased sevenfold.

The main part of this overhaul, however, has been the addition of an incredible amount of weaponry. Batteries of lasers, Class 30 autocannon, PPCs and Killer Whale missile are housed in every part of the ship, giving it tremendous offensive capability.

Not forgetting the requirement of self-defence, the designers included large pulse lasers to fend off fighters and anti-missile systems.

To date the Indefatigable is the only Quixote Type 60 in existence and with the increasing capability of the Coalition's burgeoning defence industries, she is likely to remain one of a kind.

The Indefatigable is currently deployed with the BCAF, patrolling the Coalition's borders, using her own armaments and her complement of 2 fighter squadrons to act as a deterrent to any Bandit Kings who think this new colony may just be easy pickings.
