Abstract: A projectile comprises an imaging seeker at a front of the projectile; a front warhead behind the imaging seeker; a power supply; an electronics unit connected to the power supply and comprising a microprocessor circuit board, a voltage regulator circuit board, an inertial measurement circuit board and a fuze and safe and arm circuit board, all electrically connected to each other, the microprocessor circuit board also being connected to the imaging seeker; a rear warhead, the front and rear warheads being electrically connected to the safe and arm circuit board; a rocket motor electrically connected to the electronics unit; foldable fins mounted at the rear of the projectile; a shell that encases the front warhead, the power supply, the electronics unit, the rear warhead and the rocket motor; and a maneuver mechanism disposed in the shell and electrically connected to the microprocessor circuit board.

Abstract: The present invention describes novel cyclic diol derivatives represented by formula I and II: ##STR1## in which Y represents O, S, SO, SO.sub.2, (CH.sub.2).sub.m wherein m is zero or an integer of 1 to 5, or NR.sup.a group wherein R.sup.a is hydrogen, lower alkyl, lower alkoxycarbonyl, aryl, arylalkyl or acyl;R.sup.1 represents an alkyl or alkylcarbamoyl group;R.sup.2 represents a group having formula T--(CH.sub.2).sub.n --V (X.sup.-)q, wherein T refers to a simple covalent bond, a CO, PO.sub.3.sup.-, C(O)O, or CONR.sup.b group wherein R.sup.b is hydrogen, lower alkyl or acyl;n refers to an integer of from 1 to 10;V represents either (i) the group indicated by formula --.sup.+ NR.sup.5 R.sup.6 R.sup.7 wherein R.sup.5, R.sup.6 and R.sup.7 stands for identical or different lower alkyl group, or two or three of R.sup.5, R.sup.6 and R.sup.7 taken together with the adjacent nitrogen form heterocyclic ammonio group, or (ii) the group indicated by the formula ##STR2## wherein R.sup.

Abstract: A statically stable limited range projectile utilizes a fin assembly combd with a cylindrical body and low drag ogival front end to ballistically match the limited predetermined range flight characteristics of a standard round.
