Yes, diceless. Miss/Hit/Special/Crit is determined by cross-referencing secretly-selected tactics (attack/defend/retreat) and speed difference. If you're interested, see the rules here: WarpWar Rules
Rather like BRP/RQ itself, it's best for one-against-one, or up to about half-a-dozen a side. So the players could have a fighter each, or all-in-one, or whatever. IIRC, it's quite difficult to completely destroy ships - aiding character survivability!
As I said before, adding-in complications (like crew skill-rolls) should still end up with a fairly simple system, as it's so simple to start with.
I did a similar thing a few years ago when adding skill-rolls into an on-line 'EnGarde!' combat program - and that's a similarly diceless combat system.
