Tom Clancy's HAWX's first piece of DLC, the European Assault Pack, will release on April 23 for PS3 and Xbox 360.
Extra planes include the multi-role carrier-borne version of the Dassault Rafale, the Saab-37 Viggen and two Mirage aircraft designed for nuclear strike and long-range interception.
The delta-winged FB-22 prototype bomber, based on the F-22 Raptor, also made the cut. The XA-20 Razorback featured in Tom Clancy's EndWar is in there too.
The DLC will run you 400 MS Points ($5.00) and $4.99 for PS3.
Joystiq has loads of images featuring the new planes. You'll want to have a look.
