The Port Hackburry-class Fleet Oiler is the result of a request for the development of a "medium-sized Fleet Oiler" by the Radiomatics Moorburgh Defense Force. Although its primary function is the one of a Fleet Oiler, the Port Hackburry-class Fleet Oiler can also be used as a flagship to lead smaller units (for example FACs or submarine hunters) or to coordinate CIMIC-efforts on shores (for example desaster relief efforts).


The Port Hackburry class Fleet Oiler is a classical monohull-design, reminiscent of a freighter, but with more purpose then to simply move stuff from A to B.

As a Fleet Oiler, vessels of the Port Hackburry-class are equipped to transport needed supplies for a fleet, like food, ammunition and fuel, and to relocate these supplies to other ships while still at sea (given that the sea isn't too strong).

The Port Hachburry-class Fleet Oiler is capable of transporting 2,700 tons of gasoline and fuels in ten parcels, each rated for 270 tons of ship-diesel. Two rows of five parcels are aligned along the keel, pumps and computer systems programmed to simultanously pump from the corresponding parcels in order not to destabilize the Fleet Oiler. These parcels are also capable of transporting other fluids, like aviation fuel. Although fresh water can be transported in these parcels, we don't recommend it due to residuals of the fuels and the dangers due to that. Freshwater can not only be transported (two parcels for 50 tons of water), but also can be produced aboard, recycling old water and drawing water from the sea to produce fresh water.

In the cargo bays, 400 tons of other materials can be hold, including space for four 20' Standart Containers on the oiler's deck itself. The cargo holds themselves are capable of holding ammunition and weapons in accordance with all international regulations and standarts. Two cargo bays are equipped to load frozen food, cooling systems included.

To load and unload this freight and to transfer it to other ships, the Port Hackburry-class Fleet Oiler is equipped with a total of five cranes, four rated for 15 tons each, one rated for 50 tons, plus a hoist rated for 5 tons. Both hoist and heavy crane are aligned with the keel, while the smaller cranes are at the sides of the Fleet Oiler, capable of extending the hoses for the transfer of fluids to other ships capable of crossing over a gap of ten metres (the hoses can be extended further, up to twenty metres).

The Port Hackburry-class Fleet Oiler can house and operate a fully equipped and functional staff and has a small hospital on board (including two operating theatres).

Sensors and Processing Systems

The is equipped with a single Air/Surface Search Radar, doubling as a navigational radar. It mostly serves for purposes of self-defense and coordination with incoming helicopters. They also provide valuable traffic information and information about eventually incoming missiles and aircraft for independent defensive actions. The Port-Hackburry-class Fleet Oiler also carries an Artio Battlescape Network.

However, while they do have the capacity for self defense, it is strongly advised to always have them under escort.


The Port Hackburry-class Fleet Oiler is equipped with weapons for defensive purposes. The three main deck armories can be stocked up with 5 MANPAD-Systems each, along with enough weapons to fully equip two fireteams worth of soldiers in case of an emergency. The chambers are locked via retina scanners and can be programmed by accessing the onboard Type 900 Datalink.

Most powerful weapon of the Port Hackburry-class Fleet Oiler is the Ceantar C-44 Mark III 40mm Dual Purpose Gun, is both for air defense and for defense against small watercraft. The gun and their turrets are designed to be controlled by external fire control systems, it can also use its own fire control systems, and is linked to these via Type 900 Datalink, which provides the target data needed to adjust the gun at its target. While it is a fully automatic system, the gun can be controlled manually by an external operator using the mounted camera as his 'scope'. He (or she) would then release a 40mm shell onto his target by the tap of a button. The C-44 can be used as a weapon against missiles as well, but does not perform as well against these.

The SDY-Gabha SG-1 Mark III 30mm autocannons have their grand debut onboard the Port Hackburry-class Fleet Oiler. The revolver cannon, used as a weapon against unarmoured or lightly armoured naval targets, any kind of air target or even for shore bombardement, is a whole package: Fire control via infrared and optical camera, useable both automated and manually, caseless ammunition for more bullet per round. One more advantage of the SDY-Gabha SG-1 Mark III is, that ships can easilly be reequipped with the system, since a break through the deck isn't necessary to install the weapon, just to bolt it onto the deck and to supply it with power. However, although its primary function is that of a point defense weapon, the SDY-Gabha SG-1 Mark III can not replace a dedicated CIWS and is merely a stopgap.


The Port Hackburry-class Fleet Oiler began its life as a highly ambitious project of around the same carrying capacity, but half as long and a lot lighter, proposed and send to be developed by the Radiomatics Moorburgh Defense Force. While it wouldn't have been impossible to built and construct such a vessel, the engineers of Silverport Dockyards were more then hesitant to build such a vessel, since it broke more security regulations then they were comfortable with.

So, going to the orderer with these issues, the engineers prepared to get a new design to their costumer, which later turned into the Port Hackburry-class Fleet Oiler, named after an important port in Radiomatics Moorburgh.

With four of these vessels being built for the Radiomatics Moorburgh Defense Force, and the SDF-Navy already announcing their potential interest, the Port Hackburry-class Fleet Oiler is now available for export.

Silverport Dockyards Ltd. is currently planning a few variants for the Fleet Oiler, including a variant, which is a fully fledged support and workshop ship without staff-capabilities, and another, which is a ground troop support ship/amphibious landing support ship.
