Reminds me of the Screamer Missile from Starlancer. Those were awesome. Mounting 160 of them... Mmmmm.... Who needed guns?
Anyway. In Freelancer... I dunno. At 9k damage, you'll never take equipment off of a battleship. You need three SNs to destroyer a Battle Razor, as it is. If it's for use against fighters... I dunno, there's already so many missiles and I'm not sure how dumb-fire rockets would work in Freelancer. They'd basically be really powerful guns with ammo.
