The F-111 you mean? Well it's a long range strike bomber, now only operated by the Royal Australian Air Force. It's used for deep penetration strike, battlefield strike, maritime strike and Close Air Support tasks. It is armed in Australian Service, with Mk 82/84 and BLU-109 air to ground bombs, GBU-10/12/24 LGB's, AGM-142 "Popeye" air to surface standoff missiles, AGM-84 Harpoon Anti-Ship missiles and AIM-9 Sidewinders.
Here's an F-111 armed with GBU-10 LGB and AGM-142 (underneath anyway).

The F-111 is very fast but is not capable of Mach 3. It IS capable of sustained Mach 2.5 speeds, and is capable of very high speeds at both high and low levels. For about all you'd ever want to know about F-111's,
