1. A vertically extendable and retractable turret able to rotate on a platform, comprising: an active system orientable in elevation and in azimuth,a protective cowling for the active system and for closing a caisson,wherein said turret includes means for deployment of said active system comprising a first arm and a second arm forming a deformable quadrilateral on either side of said active system, and elevation and azimuth aiming means for said active system, a first manual means for controlling deployment of the active system by activating said first arm, and a second manual means for controlling the orientation in vertically extended elevation and in azimuth of the active system by activating said second arm, and wherein said caisson forms a closed enclosure between the exterior and the interior of a platform, said caisson having an opening therein that is closed by a shutter providing access to said active system when in its retracted position. 2. A retractable turret according to claim 1, wherein said first arm is linked in rotation to a shaft integral with a support fixed to said caisson. 3. A retractable turret according to claim 2, wherein said first manual means comprise a pinion and worm assembly linked to a control organ to orient said active system in azimuth. 4. A retractable turret according to claim 3, wherein said worm assembly is integral with said shaft and thus with said first arm, and said pinion is integral with said control organ. 5. A retractable turret according to claim 3, wherein said control organ is laterally moveable thereby driving said pinion in rotation thereby driving said worm assembly. 6. A retractable turret according to claim 4, wherein said control organ is laterally moveable thereby driving said pinion in rotation thereby driving said worm assembly. 7. A retractable turret according to claim 1, wherein said second arm is linked in rotation with an angular member in the form of an L integral in rotation with a support fixed to said caisson, one end of said L being linked to said second arm and the other end of said L to a handwheel moveable for orienting said active system in vertically extended elevation. 8. A retractable turret according to claim 1, wherein said cowling is linked to said active system by at least one fastening lug forming a hinge, and spring means for pivoting said cowling to disengage a front face of said active system into a deployed position. 9. A retractable turret according to claim 7, wherein said cowling is linked to said active system by at least one fastening lug forming a hinge, and spring means for pivoting said cowling to disengage a front face of said active system into a deployed position. 10. A retractable turret according to claim 7, wherein said handwheel is movable in two directions, one direction in a horizontal plane to position said active system in azimuth or in direction, and the other direction in a vertical plane to position said active system in vertically extended elevation or in altitude. 11. A retractable turret according to claim 1, wherein said active system is orientable in elevation at an angle of between −10° and 60°.
