Boeing today unveiled a new F-15 prototype aimed at the international market with such "fifth-generation" add-ons as radar absorbent coatings, internal weapons carriage and integrated digital avionics, plus featuring a distinctive V-tail. Improving the fourth generation fighter’s profile on air-to-air radar is Boeing’s key goal for the F-15SE, which the company plans to offer to five foreign countries with an estimated market for 190 orders. Radar absorbent materials added to leading edges are designed to soften the F-15SE’s head-on radar signature. Canting both horizontal stabilizers by 15 degrees is intended to reduce radar returns to the side.
