In its second year as a legacy event, Attack Sub's attendance returned to previous levels, and even gained five brand-new skippers who had never played before.   The swiss-elim format continued this year, having been very successful last year, with three rounds of swiss play advancing eight players to single elimination. 

In Round 1 the less-favored Argentines pulled another upset in scenario D (Falklands), winning eight games to the Brit's seven. In Round 2 saw the Soviets score a minor upset over the favored Americans in scenario B (Search and Destroy), winning eight to seven, but lost decisively in the single elimination games. Only Round 3 had the favored side as the victor, with the Brits winning nine matches of scenario A (Sub Duel) to the Soviet's five.  

Four 3-0 players advanced automatically to the single elim round, tie-breakers were used to advance four of the eleven 2-1 players, a tough cut.  Kudos to Carol Caler for earning all three scenario tie-breakers, a first, and to new player Scott Kowalke for advancing. 

Players had free choice between six scenarios in single elimination, but opted for the simpler scenarios this year. Scenario B (Search and Destroy) was revisited four times, with three US wins to the Soviets one, scenario A (Sub Duel) was played twice, both Soviet wins (making up somewhat for their poor showing in the prelim rounds) and scenario D (Falklands) was played once, netting another Argentine win.

Long-time Attack Sub players Dave Sidelinger and Jim Fleckenstein finally got their due this year. Both advanced to single elimination as 2-1 players, then proceeded to win their quarter-final games against unbeatens (Carol Caler and Bob Heinzmann respectively), and their semi-final games against 4-0 players (Andrew Cummins and Jim Doughan).

In the Final, Dave selected A (Sub Duel) as the scenario and Jim picked the Brits, giving Dave the slightly weaker Soviets. The Brits got off to a good start, fixing their sensor malfunction with their first draw, then both sides began a sonar duel, both gaining minimum contact level 1 on the other. The Soviets took a quick shot with the Ivan Rogov, and a lucky hit sank the Valiant immediately. Down to one sub, the Brits aggressively went active with the Swiftsure, quickly gaining level 2 contact on the Rogov and level 3 on the Skvortsov. Without sensor cards, the Soviets closed range with the Rogov to contact 1, fired a torpedo that missed, then a second that hit, but only did one sensor and one attack damage. Wounded but still in the fight, the Swiftsure fired back at contact 4, an almost certain hit, but only drew an attack malfunction. The Rogov closed to contact 3 and in a close-range knife fight both subs exchanged torpedoes which missed, then Rogov got the final hit, sending Swiftsure to the bottom. Both skippers played boldly but luck favored the Soviets this time. Congratulations to Dave Sidelinger, the newest Attack Sub champion!
