Turret with retractable protective roof

An armoured vehicle turret that can accommodate a crew including a gunner, comprising:

• a fixed roof with an opening;
• a retractable protection system comprising an armoured cover or dome, that is pivotably movable about a horizontal axis and/or in vertical translation,
• the retractable protection system being configured to assume:
• a first position in which the retractable protection system is retracted against the roof and ensures a closing of the opening;
• a second partial open position in which the retractable protection system is partially deployed in vertical translation upwards so as to protect a soldier in an observation position;
• a third partial open position in which the retractable protection system is partially deployed in vertical translation upwards more so than in the second position, so as to protect the soldier in a sniper position;
• and a fourth fully open position in which the retractable protection system is fully deployed by pivoting and/or upward vertical translation uncovering the opening to allow evacuation of the crew;
• and
• a motion mechanism ensuring motion of the retractable protection system between the first position, second partial open position, third partial open position, and fourth fully open position,
• wherein, in the second partial open position, the retractable protection system uncovers a lateral peripheral space closed by protective loophole plates, so as to permit the soldier to take an observation position of up to 360°.
