What follows is informally known as the Great Turkey Shoot of '76. 21st Fleet, under Fleet Admiral Weston, was the spearhead of the Imperial assault. The Phalanx Photon is developed.
2377 - The sheer scale of Borg space made rapid victory over the confused drones impossible. Then, without warning, the Borg began to reactivate. Their tactics changed. Instead of charging in among a superior enemy, the Borg began to lay traps. Instead of fighting to the last cube, they fought holding actions while inflicting casualties on Imperial ships. They also began to be able to use their holding beams through the upgraded Imperial shields. As a result, the Borg begin to push Imperial fleets out of their space. Imperial scientists built the first regenerative shield. Pulse Phaser orb batteries are developed.
2379 - Attack on second Borg Unimatrix succeeds. Borg numbers dwindled to low to allow them to recover against the weight of Imperial ships closing in on them from all sides. Prometheus and Nova class are authorized for production. Ablative armor generators are developed; it is an invaluable second line of defense after shields have been breached. Only used on capital vessels at this time. To help increase the amount of firepower brought against Borg targets, the fighter/carrier combo again makes an appearance in the Imperial order of battle after a long hiatus.
2381 - Final Borg vessel in the Delta Quadrant is destroyed. Borg are declared wiped out by the Terran Imperium.

Much of it is used to jump start the Empire's rebuilding plans. Bastion class monitors designed and put into production.
2382 - Quantum Slipstream Drive is acquired from a conquered Delta Quad species. Refit begins on all surviving front line vessels. First workable phase cloaking device is developed. It is added to the refit of Bastion class ships of the Terra Defense Fleet and those in the Alpha Centauri defense fleet. It is also installed in all Section 31 Black Fleet vessels, including the Black Fleet's uprated flagship, the Terra-class BFV Assassin.
2391 - Borg tech has allowed the Imperial Fleet to rebuild to almost 3/4s of its pre war strength. But there are still large areas that are lightly patrolled or have no patrols at all. Deep in a fragmented Borg database, they found their enemy, the Goa'uld who inhabit six Galaxies and have the majority of those planets under a death grip. The Goa'uld are declared 'Enemies of all species'. The 21st Fast Attack Fleet is sent to establish a Beachhead in that Galaxy.
