Did someone tell you, how difficult to patrol Omicrons? This is a space, where happens literally everything and every Order agent risks his life to make Sirius borders safe. Once you launched from the station or Akabat and you may never come back.
Three fighters had their regular patrol along their usual route Akabat - Tarancon - Freeport-11 - Tarancon - Taba, and everything was fine. No Core or Nomad encounters throughout the route. After little rest on Freeport, squadron decided to fly back and while they flew through nebula in Omicron Minor, navigation systems malfunctioned and charted wrong direction without warning. Surething, pilots didn't notice anything until agent Williams realized, they flew into the area, where scanners efficiency were ultimately reduced. They almost didn't see each other even on close distance between fighters. Approximately, 30 minutes later, patrol stumbled upon large warship, hidden in highly dense nebula and asteroids. After quick analysis, they revealed, there was "Bullhead"-class APM vessel, but disabled and abandoned for a years. There were nothing really worth to survey: hardware, software, equipment, valuable materials - everything has been removed from ship's board. Except two disabled unusual turrets on battlecruiser's front. They looked unlike usual battleship primary cannons there were used before revising and adapting ships for new weaponry. Unfortunately, they had no chance to test or remove their finding, because cannons were too large to be transported by three fighters.

A day later, we sent a cruiser to the Bullhead's cordinates that able to sefely remove turrets. They were large, even larger than Cerberus-class cannons designed for battleships. I wonder, how did they adapt those cannons slightly unsuitable for assault cruisers.
On Carthage, engineers revealed, that rare weapon "Gale"-class has been designed and built by Corsairs long time ago. According rumors, Corsairs have made small amount of that kind of weaponry and production has been stopped by various reasons. Then, Core had managed to adapt weapon on their battlecruiser.
After several tries to install cannons on test platform, testers did note their technical parameters and abilities.
Advantages over other well-known battleship heavy cannons:
1. Range. This weapon is able to shoot their large heat bullet on extremely long distance, almost same to heavy mortars.
2. Piercing force is much higher than Cerberus or modern Hellbore cannons. Of course, every shot requires a strong powercore, but this is wasn't a real problem.
Remains only to find good employment for these two beauties.
