The mission occurs in several stages, is relatively drawn out, but is also for the most part straightforward. The first task is to use the hydrofoils and dolphins to protect the salvage ship until the time runs out. When ground units attack, switch the hydrofoils to weapon neutralizers to keep the dolphins safe while they attack.
The next phase involves the destruction of the first radar ship. Just move the spies into the power generators one by one, and wait for Natasha to destroy each one before moving to the next. When the final generator is down, just instruct her to attack the ship itself.
The third phase has you in control of Tanya, and plays out almost exactly as the last phase. Clear a path with Tanya, and have the engineers capture each power gen to disable the defenses near the next generator. After all generators are captured, have Tanya swim out to C4 the radar ship. There are some health packs scattered about if she takes too much damage.
The final phase of the mission now begins. Start by capturing the oil derricks and resource locations near the 2 islands you cleared with the commandos earlier. You can construct a barracks on one of these islands to produce engineers and troops to be para-dropped later. Build a strong naval force with hydrofoils and aircraft carriers with some destroyers to fight off enemy navies. The aircraft carriers are great for hitting their naval structures, or clearing the defenses on the fortress itself, while the hydrofoils will help fend off the air counterattacks.
Build 2 airfields on the land next to a barracks, and start building century bombers. If you build the airfields on water, infantry will not be able to load into the bombers. Now use your naval forces to clear the anti-air capable turrets on the fortress, using the aircraft carriers for this task. Once a large number of the AA turrets are down, use the century bombers and make round trip attacks on the rest of the turrets and other base structures. When these defenses have been weakened, pick a drop zone and start bringing troops with as many bombing runs as possible. The easiest spot to do this may be the right side of the island, since it is closer to your starting base.
Once you have enough forces on the fortress, you can capture some buildings if you want to build vehicles on the fortress, or work with the infantry and bombers to clear a path to the central ramp of the fortress, where from there you can secure a spot for both you and the co-commander to move assault destroyers and stingrays onto the fortress for support. Once the area around both power cores is clear (you can rush this by focusing on necessary defenses and dropping engineers right on top of the power core locations) they will be destabilized causing the entire fortress to be destroyed, and this mission declared a victory.
