A fighter bomber aircraft having a rhomboid airframe with a dihedral bottom surface and a top surface designed as an airfoil. The rhomboid cross-sectional configuration gives it increased lift, stealth characteristics, and enhanced load-bearing capacity. It also has two central tubes stacked on top of one another and extending front-to-rear, with the upper tube extending part way through the airframe and preferably housing a pilot, guns forward from and in line with the pilot, a gear/equipment compartment behind the pilot, and fuel tanks positioned behind the gear/equipment compartment. The lower tube extends substantially throughout the airframe and preferably houses the air-intake for the engine, radar, nose gear, bombs, and rear engine. The aircraft has no conventional wing structure and its dihedral bottom surface allows it to make wheels-up emergency landings on water and hard runway surfaces. In addition, rockets can be optionally mounted on the top of the lift area.
