140 plus specially-designed gravity cannon ships, other than plasma reactors and energy shield generators, they had practically no other devices on it. For example, weapons and residential amenities. In other words, the whole spaceship itself was designed to fit the gravity cannon.
Each gravity cannon spaceship's firing range was about 3,400 kilometers around itself. In other words, everything within these 3,400 kilometers will be affected by the tidal force. In fact, the actual range of the cannon was 60,000 kilometers, but the 3,400 kilometers was where the real power of the gravity cannons could be felt.
The range of 140 gravity cannon spaceships could easily overlap the battleships, and each spaceship's 3,400 kilometers range would be expanded greatly. If the 140 spaceships were completely spread out, the range could cover a giant sphere of 2,000,000 kilometers in diameter. This distance is about five times the distance between Old Earth and the Moon!
