1. A projectile device for piercing armor, the projectile device being fired from the barrel of a gun, the projectile device comprising: (a) a shell; and (b) a cartridge associated with said shell prior to firing, said cartridge containing a launch propellant for accelerating said shell along the barrel of the gun to a muzzle velocity, wherein said shell includes: (i) a cruise rocket motor configured for maintaining a substantially constant cruise velocity of said shell for a first period after leaving the barrel of the gun; and (ii) an acceleration rocket motor configured for accelerating said shell from said cruise velocity to a penetration velocity in a final stage of flight of the shell. 2. The projectile device of claim 1, further comprising an armor-piercing rod situated within said shell for piercing armor.3. The projectile device of claim 2, further comprising a penetrating device coupled to said shell for penetrating a reactive target having reactive armor.4. The projectile device of claim 3, wherein said penetrating device includes an advance projectile associated with said shell, for neutralizing reactive armor of a target.5. The projectile device of claim 4, wherein said advanced projectile is a bullet.6. The projectile device of claim 1, further comprising an electronic system associated with said shell for altering a trajectory of said shell during flight of said shell.7. The projectile device of claim 6, wherein said electronic system further comprises: (a) a sensor, for detecting a target; and (b) a guidance system for controlling the trajectory of said shell. 8. The projectile device of claim 7, wherein said sensor is responsive to a radar signal.9. The projectile device of claim 7, wherein said sensor is responsive to radiation emission of said target.10. The projectile device of claim 1, wherein said cruise rocket motor is activated substantially at the beginning of flight of the projectile.11. A method for propelling a shell fired from the barrel of a gun to pierce armor of a target, the method comprising: (a) employing launch propellant for accelerating the shell along the barrel of the gun to a muzzle velocity, said launch propellant being located within a cartridge associated with the shell prior to firing; (b) employing a cruise rocket motor located within the shell for maintaining a substantially constant cruise velocity of the shell for a first period after leaving the barrel of the gun; and (c) employing an acceleration rocket motor located within the the shell for accelerating the shell from said cruise velocity to a penetration velocity in a final stage of flight of the shell. 12. The method of claim 11, further comprising the step of penetrating armor of the target with the shell.13. The method of claim 12, further comprising the step of neutralizing reactive armor of said target prior to said penetrating.
