I can’t speak for what actually happens, or what even what SOP in the armed forces might be in this situation.
SO…I googled it. Here’s the levels of complexity involved in a Tomahawk missle strike:
-
Command and Authorization (Top-Down Flow)
Authorization: The process starts with a decision by the President, often passed through the National Security Council to the Secretary of Defense, and then to the Chairman of the Joint Chiefs of Staff. Command Channel: The Joint Chiefs convey the order to a regional commander (e.g., U.S. Central Command or Indo-Pacific Command). Execution Order: The regional commander transmits the target information and engagement requirements to the specific launch platforms (ships or submarines).
-
Transmitting the Order to the Specialist
Secure Communications: The order is sent via secured, encrypted digital communications to the vessel’s Tomahawk Strike Coordinator (TSC) or equivalent senior operator. TTWCS Integration: The data is directly integrated into the Tactical Tomahawk Weapons Control System (TTWCS) on board. Mission Planning: The TTWCS allows the crew to plan the route or receive pre-planned, digital target coordinates, known as a Missile Sequence Number (MSN) task.
-
Action by the Specialized Operator (Launch Team)
Mission Assignment: The firing platform’s operators receive a digital tasker, which includes primary and sometimes backup assignments. Validation: Specialists on the bridge/combat center verify the target and launch authorization. Targeting Data Entry: The TTWCS is updated with the new target data, which may include GPS coordinates. Block IV missiles can be reprogrammed in-flight, but the launch command requires pre-defined parameters. Launch Sequence: The operators execute the final launch sequence, which involves the missile being ejected by a solid-fuel booster from the Vertical Launching System (VLS).
SO, at which point should the crew have refused the order? Where does the blame lay?
Dunno what to tell ya. The process is what it is. What we are seeing is a failure of of the entire system of checks and balances. The legislative and judicial branches refuse to reign in the executive branch. IMHO, our Congress members and Supreme Court are more culpable for those girls’ deaths than the soldier who fired that missile.
