Time is 1,440 build points divided by build power. Drain is mass and energy per second while it is building, so more build power finishes sooner and costs the same total, but pulls harder on the economy.
Carries anti-torpedo as well as torpedoes, which most T1 submarines do not, so it survives a torpedo exchange its counterparts lose.
