Star Fleet Battle Group Omega

Star Fleet Battle Group Omega was the code name for an emergency fleet put together by Admiral Kathryn Janeway to offer the Enterprise-E assistance in destroying a Reman thalaron weapon in 2378.

Battle of the Bassen Rift

 * See also main article, Battle of the Bassen Rift.

Upon receiving news from Captain Jean-Luc Picard of the existence of the weapon, Admiral Janeway immediately ordered the vessels nearest to his position to the Bassen Rift, hoping the interference would stop the Remans from calling for reinforcements. The effects would also prevent the Scimitar from detecting the hiding fleet, in hopes of a surprise attack.

Unfortunately, the Enterprise was attacked before they could get to the fleet, and the effects of the Bassen Rift also disabled their communications so they were unable to contact the fleet.

Several minutes after the Enterprise's expected arrival time had passed, the fleet moved to find their last known position. Although they arrived late, the seven starships found the Scimitar and it's thalaron weapon destroyed. Although the Enterprise had suffered heavy damage and casualties, the fleet joined a Romulan warbirds attempt to assist the Enterprise, towing her out of the rift until her engines could be repaired.

Background

 * The reason so many class-prototypes were present (3 out of 7 of the ships) was because the Galaxy, the Intrepid, and the Nova were all attending a ceremony for the ground breaking of a construction yard near-by.

Curiously, the graphic shows Starfleet to be two words in this instance.
