By far the most numerous production run. The Block 1 showed a massive upgrade on the block 0's. With slanted pods allowing Cannons better arcs of fire and an increased air-wing the offensive power was much improved. In addition, the computer systems were far more advanced, and the Block 1's were the first Battlestars to be designed specifically to be operated using networks, unlike the Block 0's which had treated them as more of an added luxury. This meant the crew could be massively reduced.
