The Composite Warfare Commander (CWC) Concept

In a modern U.S. Navy Carrier Strike Group (CSG), command and control operates under the Composite Warfare Commander (CWC) concept. This structure assigns functional call signs to different warfare commanders, preventing the overall strike group commander from becoming overwhelmed during high-intensity combat.

AW — Air Warfare Commander (Anti-Air Warfare / AAW)
AS — Surface Warfare Commander
AX — Undersea Warfare Commander (USWC)
AQ — Information Warfare Commander (cybersecurity, communications, electronic warfare, and space integration)

Modern Naval Battle Group Command Structure

Why is the Submarine Commander Called AX?

The letter "X" is used by naval doctrine to denote the subsurface domain in tactical communications. The fast-attack submarines (SSNs) attached to the battle group act as forward scouts for AX, hunting enemy threats well ahead of the surface ships.

Navy Space Designators

The Navy handles space operations through two distinct identifiers. The U.S. Navy commissions Maritime Space Officers (MSOs) under the Information Warfare Community using the permanent designator 1870. For standard sailors or officers who perform space duties but belong to other communities, the Navy uses VS5 through VS8 (Space Operations) and VR1 through VR3 (Space Acquisition) tracking codes.

Within the CIC watch framework: there is no dedicated space watchstander. The TAO relies on external satellite data feeds managed by the ship's Information Warfare and Communications team, funneled directly into the Aegis combat system display.

The TAO and ASAT Engagement

The Air Warfare (AW) team is the group that actually fires and controls an Anti-Satellite (ASAT) weapon. When the USS Lake Erie destroyed a failing spy satellite during Operation Burnt Frost in 2008, the tracking, targeting, and firing sequence was executed directly through the AW watch team for three reasons:

1. The Weapon Belongs to AW — The SM-3 (Standard Missile 3) is housed in Vertical Launch System cells on Aegis cruisers and destroyers. The Missile System Supervisor and Aegis Fire Control watchstanders sit in the AW section of the CIC.

2. The Radar Tracking Belongs to AW — To hit something in space, the ship must use its SPY-1 or SPY-6 radar to track the target at extreme altitudes. The AW watch team manages the radar's power resources, treating a low-Earth orbit satellite essentially like an extremely fast, high-altitude ballistic missile track.

3. Space Does Not Pull the Trigger — Because space cannot actively defend itself or fire physical weapons down at a target from a surface ship, any kinetic action aimed upward naturally falls to the AW team.

The engagement sequence: U.S. Space Command calculates the satellite's orbit and passes firing telemetry to the ship. The TAO receives Authorization to Engage from national command authorities. The AW watch team executes the launch, firing the SM-3 out of the deck and guiding it into space.

AX: The Most Mobile Commander in the Battle Group

Historically the Cruiser was the "double-hatted" powerhouse of the Battle Group — AW and AS commanders sat side-by-side on the same ship. There was no independent AX because anti-submarine warfare was tethered to whatever hull had the best sonar assets at that moment.

With modern data links like Link 16 and Cooperative Engagement Capability (CEC), the physical location of the commander no longer dictates where the sensor data is. The AX commander can sit in the CIC of an entirely different ship and view a real-time composite picture of the underwater fight fed by remote sonobuoys, towed array sonars from multiple destroyers, and dipping sonars from MH-60R Seahawk helicopters.

The Undersea Warfare Commander (AX) is almost always the Commander of the Destroyer Squadron (DESRON) — an embarked unit designed to be completely mobile. Putting AX on a mobile Destroyer also keeps the most dangerous underwater hunting tracks away from the Aircraft Carrier, pushing out to the fringes of the Battle Group where enemy submarines are most likely to hide.

Soviet Doctrine and the Modern Saturation Threat

The core of this tactical framework — the Aegis Combat System, the TAO structure, the separation of AW/AS/AX, and the automated engagement loops — was specifically engineered in the 1970s and 1980s to survive Soviet "saturation" doctrine. The Soviet plan was to overwhelm a Carrier Battle Group by launching hundreds of cruise missiles simultaneously from Backfire bombers, Oscar-class submarines, and surface combatants.

Today adversaries like China have not abandoned that strategy — they have vastly modernized and scaled it. A modern adversary will use a multi-axis, multi-domain saturation attack combining:

Anti-Ship Ballistic Missiles (ASBMs) — Weapons like the DF-21D or DF-26 dropping from the edge of space at hypersonic speeds (Mach 5 to Mach 10) from a near-vertical angle.
Hypersonic Glide Vehicles (HGVs) — Low-altitude missiles that travel incredibly fast but skip and weave along the atmosphere underneath traditional ballistic missile tracking radars.
Traditional Cruise Missiles — Hundreds of low-flying sea-skimming missiles fired from overlapping swarms of aircraft, submarines, and land-based launchers to physically exhaust the ship's ammunition.

To survive this, the AW team relies on the same automated logic developed during the Cold War, accelerated by vastly superior processing power. The TAO can place the Aegis system into automated modes — if the radar detects a threat matching specific hostile criteria, the system will automatically track, assign a missile, and fire without waiting for a human. Weapon layering allows SM-3s for ballistic missiles in upper space, SM-6s for fast-moving upper atmosphere targets, and SM-2s or ESSMs for sea-skimmers close to the ship.

The biggest flaw is not the ship's ability to track targets but its ammunition capacity. A destroyer only has 96 Vertical Launch System cells. A modern saturation attack aims to force the AW team to empty their magazines, leaving the carrier defenseless against the next wave. This is why the Navy is urgently prioritizing directed-energy weapons and electronic warfare to blind incoming missiles without burning physical ammunition.

The Cruiser Question

The 1987-era Ticonderoga-class Cruiser was explicitly built as a high-capacity, heavy-hitting command ship with 122 VLS cells. An Arleigh Burke-class Destroyer has only 96. When a destroyer is tasked with ASAT or Ballistic Missile Defense missions, it must dedicate several of those cells to carry large SM-3 missiles, drastically reducing the number of Tomahawks, SM-2s, and ESSMs it can carry for standard threats.

In my opinion the Cruiser structure as it was in 1987 — a key component of any strike force — should have ample supply of weapons dedicated specifically for ASAT. That is not negotiable. Destroyers, while they might have the capability to shoot a satellite, should never have that as their primary mission by any stretch.

The long-term replacement, the DDG(X) Next-Generation Destroyer, aims to restore the massive hull size, advanced radar power, and larger VLS capacity. Until those ships hit the fleet in the 2030s, destroyers will continue to be stretched thin acting as jacks-of-all-trades across sea, air, and space.
