   en.wikipedia.org/wiki/122_mm_howitzer_2A18_(D-30)

   With its three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the countries of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces. The barrel assembly of the 2A18 gun is used in the 2S1 self-propelled howitzer ...

3. Stabilator - Wikipedia

   en.wikipedia.org/wiki/Stabilator

   Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).

4. Gun stabilizer - Wikipedia

   en.wikipedia.org/wiki/Gun_stabilizer

   There are many forms of gun stabilization. The simple single-plane stabilizer only stabilizes on a vertical axis, and the two-plane stabilizer stabilizes both the vertical and horizontal axis. The mechanism usually includes an angular reference device such as a mechanical or optical gyroscope and servomechanisms. In the case of a tank, one ...

7. Stabilizer (ship) - Wikipedia

   en.wikipedia.org/wiki/Stabilizer_(ship)

   The fin stabilizer had been patented by Motora Shintaro of Japan in 1922. [7] [8] The first use of fin stabilizers on a ship was by a Japanese cruise liner in 1933. [9] From the late 1930s the British were actively installing the Denny-Brown fin stabilizers onto their warships (over 100 installations by 1950). [7]

8. Vertical stabilizer - Wikipedia

   en.wikipedia.org/wiki/Vertical_stabilizer

   The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...

9. Elevator (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Elevator_(aeronautics)

   Supersonic aircraft usually have all-moving tailplanes (stabilators), because shock waves generated on the horizontal stabilizer greatly reduce the effectiveness of hinged elevators during supersonic flight. Delta winged aircraft combine ailerons and elevators –and their respective control inputs– into one control surface called an elevon.
