Min crew on a javelin is 12 and min crew on an Idris is 8 and they are currently the largest ships that the players will eventually have access to, players wont be able to fly these ships until after SQ42 is released, there is not going to be a small server cap when the game is released so comments about it are pointless.
Ships when heavily damaged in SC will stop responding to controls and be disabled well before they should blow up, you wont just be able to fight until the second your ship blows up.
