This is one part wishful thinking (I'm terrible at combat) and one part lore. Science vessels like the USS Grissom are meant to be unarmed, as their purpose is collecting scientific data not fighting. I understand that there's a war on, but still. The game could be changed so said science vessels are never without an escort from a larger, better-armed ship. *shrugs*
