A liner assembly for an explosively formed projectile device may include a reactive material liner and a primary liner configured to form into a projectile responsive to initiation of an explosive material. The reactive material liner may be configured and formulated to increase the velocity of the projectile after formation thereof. An ordnance device for generating an explosively formed projectile may include a case, an explosive material, and a reactive material liner and a primary liner configured, in combination, to form into a projectile. An explosively formed projectile may include a deformed primary liner and a deformed reactive material liner having an ignited portion increasing the velocity of the projectile. Methods of explosively forming a projectile may include explosively expelling a primary liner and a secondary liner and increasing the velocity of the projectile by combusting at least a portion of the secondary liner.
