1. An actuation assembly comprising: a casing;a plurality of linear actuators coupled to the casing and symmetrically arranged about a central axis, each of the linear actuators having first and second components and being configured to move the second component thereof relative to the first component thereof along a respective first axis; anda plurality of translational member sets, each being coupled to the second component of a respective one of the linear actuators and the casing and being configured such that when the second component of the respective linear actuator moves along the respective first axis, a selected portion of the translational member set moves substantially along a respective second axis, each of the second axes substantially orthogonal to the respective first axis,wherein: the translational member sets each comprise at least first and second members, the first member comprising the selected portion of the respective translational member set and a first engagement formation and the second member being coupled to the casing to rotate about a third axis and comprising a second engagement formation a distance from the third axis and mated with the first engagement formation, andthe first and second engagement formations each have a length as measured in a direction substantially parallel to the first axis, the length of the first engagement formation being substantially different from the length of the second engagement formation. 2. The actuation assembly of claim 1, wherein the first and second engagement formations each have a width as measured in a direction substantially parallel to the second axis, the width of the first engagement formation being substantially the same as the width of the second engagement formation. 3. The actuation assembly of claim 2, wherein the second engagement formation has a length that is substantially less than the length of the first engagement formation and the first and second members are arranged such that the second engagement formation translates between first and second ends of the first engagement formation when the second component of the respective linear actuator moves along the respective first axis. 4. The actuation assembly of claim 3, wherein each translational member set further comprises a third member being rotatably coupled to the second member and the second component of the respective linear actuator. 5. The actuation assembly of claim 1, wherein each of the linear actuators comprises a rotary motor and a ball screw. 6. The actuation assembly of claim 5, wherein the casing is shaped to prevent rotation of the ball screw of each of the linear actuators during operation of the respective rotary motor. 7. A control system for a maneuverable kill vehicle comprising: a pressurized fluid source configured to provide a pressurized fluid;a plurality of valves in fluid communication with the pressurized fluid source; andan actuation assembly comprising: a casing;a plurality of linear actuators coupled to the casing and symmetrically arranged about a central axis, each of the linear actuators having first and second components and being configured to move the second component thereof relative to the first component thereof along a respective first axis, and each of the linear actuators comprising a rotary motor and a ball screw and the casing is shaped to prevent rotation of the ball screw of each of the linear actuators during operation of the respective rotary motor; anda plurality of translational member sets, each being coupled to the second component of a respective one of the linear actuators and the casing and being configured such that when the second component of the respective linear actuator moves along the respective first axis, a selected portion of the translational member set moves substantially along a respective second axis, each second axis being substantially orthogonal to the respective first axis,wherein the selected portion of each of the plurality of translational member sets is coupled to a respective one of the plurality of valves such that the movement of the selected portion of the valve causes an adjustment in a flow rate of the pressurized fluid through the valve,wherein the translational member sets each comprise at least first and second members, the first member comprising the selected portion of the respective translational member set and a first engagement formation and the second member being coupled to the casing to rotate about a third axis and comprising a second engagement formation a distance from the third axis and mated with the first engagement formation, andwherein the first and second engagement formations each have a length as measured in a direction substantially parallel to the first axis, the length of the first engagement formation being substantially different from the length of the second engagement formation and the first and second engagement formations each have a width as measured in a direction substantially parallel to the second axis, the width of the first engagement formation being substantially the same as the width of the second engagement formation. 8. The control system of claim 7, wherein the second engagement formation has a length that is substantially less than the length of the first engagement formation and the first and second members are arranged such that the second engagement formation translates between first and second ends of the first engagement formation when the second component of the respective linear actuator moves along the respective first axis. 9. A maneuverable kill vehicle comprising: a frame;a pressurized fluid source connected to the frame configured to provide a pressurized fluid;a plurality of valves in fluid communication with the pressurized fluid source;an actuation assembly comprising: a plurality of linear actuators coupled to the frame and symmetrically arranged about a central axis, each of the linear actuators having first and second components and being configured to move the second component thereof relative to the first component thereof along a respective first axis; anda plurality of translational member sets, each being coupled to the second component of a respective one of the linear actuators and the frame and being configured such that when the second component of the respective linear actuator moves along the respective first axis, a selected portion of the translational member set moves substantially along a respective second axis, each of the second axes substantially orthogonal to the respective first axis, an angle between the respective first axis and the respective second axis being at least 45 degrees,wherein the selected portion of each of the plurality of translational member sets is coupled to a respective one of the plurality of valves such that the movement of the selected portion of the valve causes an adjustment in a flow rate of the pressurized fluid through the valve; the translational member sets each comprise at least first and second members, the first member comprising the selected portion of the respective translational member set and a first engagement formation and the second member being coupled to the casing to rotate about a third axis and comprising a second engagement formation a distance from the third axis and mated with the first engagement formation, andwherein the first and second engagement formations each have a length as measured in a direction substantially parallel to the first axis, the length of the first engagement formation being substantially different from the length of the second engagement formation and the first and second engagement formations each have a width as measured in a direction substantially parallel to the second axis, the width of the first engagement formation being substantially the same as the width of the second engagement formation; anda controller in operable communication with the linear actuators and configured to selectively cause the second components of the linear actuators to move relative to the first components of the linear actuators. 10. The maneuverable kill vehicle of claim 9, wherein when the pressurized fluid flows through each of the plurality of valves, a force is exerted on the frame. 11. The maneuverable kill vehicle of claim 10, further comprises a second plurality of valves in fluid communication with the pressurized fluid source and wherein the second plurality of valves and the pressurized fluid source are configured such that when the pressurized fluid flows through each of the second plurality of valves, a second force is exerted on the frame, the second force being less than the first force.
