Strategy

This is straight from the Nexus forum. I found that Tanaka already wrote an excellent guide for this mission, so I took the liberty of presenting his posting here. Thanks Tanaka.
Next, at mission start, Do Not move towards the station, stay right where you are. Send your fighters to protect their individual mothership, and wait for the back-up fleet to arrive. Just let the Kissaki blow themselves up. After your fleat arrives, immediately power up your shields, and send heav each set of fighters to protect their own mothership. Next, use manual control to have each of them move in on your cruiser. By now, the enemy should have jumped in with their battleship. Shortly, they will send a wave of bombers and gun-bots. Use your fighters to intercept these fighters and protect whatever ship they target (usually #6 or #2 for me). After the fighters are destroyed, dock your fighters, and leave them docked. Power up each weapon on your ships individually, and target all Crisis torpedos on the station. Move to artillary range, but make sure your heavy cruiser is the closest (use manual movemen if you have to). With crisis torpedos firing from every ship, the energy shield drops in no time. As soon as it drops, the enemy vessels will begin to move in on your position. Do not, I repeat, DO Not Engage the enemy! Keep firing at the station to keep its shield down. Generally, the destroyer will be the first to reach you. As soon as it reaches a range of 11, target every energy draining weapons you have on the little guy. As soon as his shields are down, hit him with everything EXCEPT your dragonslayer. Remember, Do Not Move, just target the enemy and let your firing arcs do the rest. By now, the Fort shield will likely be back up, the destroyer hopefully dead, and the two cruisers and battleship are either inside or returning to the Fort Shield. With the destroyer Out of Commision, target your Energy Torpedo's on the Fort shield, and bring it down again. As soon as it drops, being moving your ships in on the Battleship. Fire your Dragonslayer at it. The big beast will take massive damage. Make sure that your little destroyer stays back to guard one of your larger ships, or she'll likely be taken out by enemy fire. Now, with the battleship's shield down, nail it with every physical weapon you have, and make sure you also target it with energy torpedo's to keep its shield down. As soon as it goes critical, turn your ships around and get out of there, moving to at least 17-18k from the station. Evaluate your fleet, and see how healthy you are. If you did it right, you just elliminated their biggest ship wtih little to no losses. Now, just figure out which of your ships are still in fighting shape, and move them to about 14K from the fort shield, with your lessor ships at 15k. Hit the fort shield with energy torps. After it drops, keep hitting it with torps and wait for the cruisers to come over. As soon as they open fire, pick the closest one, and hit it with energy draining weapons. If you want, you can also send out your figters to soften its twin up. After the cruiser's shield goes down, make it go boom. Remember, don't move any closer to the station or it will open fire on you. If one of the cruisers escapes back to the station, just drop the fort shield again, and elliminate the cruiser like you did the other. After you have taken out both cruisers, drop the Fort shield yet again, and move in on the station. Make sure at least one ship has its sensors up, (preferably your destroyer,) and detect and destroy the last enemy vessel. Take out any weapons platforms you find as well. If need be, put up fighter squadrons to shoot down enemy missiles, and then target the fighters on the station. Next, just target the station with whatever weapons you have left, and hit it till they start screaming. As soon as they do, stop shooting, or you might fail the mission due to destroying the station.
Congratulations!
