SSG(X) Design – VT Team 3 Page 8 2 Mission Definition The SSG(X) requirement is based on the SSG(X) MNS and Virginia Tech SSG(X) ADM in Appendix A and Appendix B respectively with elaboration and clarification obtained by discussion and correspondence with the customer, and reference to pertinent documents and web sites referenced in the following sections. 2.1 Concept of Operations The concept of operations is based on the MNS and ADM for the Guided Missile Submarine to provide a nonnuclear platform for covert strike and ISR. It will snorkel using open-cycle during transit and operate on AIP and batteries on station. The SSG(X) must be able to operate in vulnerable remote littoral regions. This vulnerability requires a non-nuclear platform. The submarine will engage in threats in cooperation with other forces; it will function as a platform for time sensitive and covert strike. The SSG(X) will support Anti-Air Warfare (AAW) by launching missiles cued by surface platform; the SSG(X) will conduct Anti-Submarine Warfare (ASW) using torpedoes with detection from sonar and tracking; the platform will launch Harpoon missiles and torpedoes for Anti- Surface Warfare (ASuW) and use sonar detection and tracking for identification of enemy surface ships. In accordance with “Forward from the Sea,” the submarine will project power ashore for Strike operations using TLAM. The SSG(X) will support a single SEAL team. The SSG(X) will perform ongoing ISR. The submarine will need to perform mine countermeasures involving detection, avoidance and neutralization. This will be done with Unmanned Underwater Vehicles (UUVs) and Autonomous Underwater Vehicles (AUVs). During ISR operations, it will be necessary for the submarine to avoid and neutralize attack from enemy submarines and avoid detection from patrol craft. 2.2 Projected Operational Environment (POE) and Threat The projection of force against enemy nations near geographically constrained bodies of water requires the SSG(X) to operate using AIP in littoral regions worldwide. During the mission, the submarine may encounter dense contact by the enemy. The submarine will need to protect itself from 1) conventional and nuclear weapons, 2) antiship mines, 3) contact with and attack from surface ships and diesel and nuclear submarines, and 4) attack from air or land. The SSG(X) will be able to perform evasive or defensive measures in littoral regions in response to these threats. The SSG(X) must be able to transit in the open ocean while snorkeling. The submarine should be suitable for all weather and be able to withstand sea states 0 through 9. Compromises will need to be made in the design to produce a submarine seaworthy enough for transoceanic tours and agile enough to effectively perform missions in littoral regions. 2.3 Specific Operations and Missions The SSG(X) is required to perform two major missions. Under each of these missions, the SSG(X) is required to conduct MIW, ASW, ASuW and AAW scenarios. AAW capabilities are limited to launch; the SSG(X) will work in concert with surface ships that detect and track enemy aircraft. The SSG(X) is capable of performing all four warfare types with a high degree of stealth by utilizing AIP. The first major mission is to conduct ISR, which includes Special Operations. These missions can include conducting visual reconnaissance, recovering assets (human or electronic), and eliminating targets. The intelligence sides of ISR entails gathering information by intercepting electronic conversations or tapping into hardwire lines. The other major mission the SSG(X) will perform is a missile launch. The objective of this mission will concentrate on a land attack; however, the SSG(X) will not be limited to land attack missile launches. The SSG(X) is also capable of targeting ships with an ASuW missile launch, missiles with an AAW missile launch, and a submarine with an ASW torpedo launch. No matter what type of missile launch scenario, the SSG(X) is designed to launch in a time sensitive scenario as well as being covert. 2.4 Mission Scenarios Mission scenarios for the primary SSG(X) missions are provided in Table 3 and Table 4. The ISR Mission departs from the continental United States and covertly travels to a hostile area to conduct intelligence, surveillance and reconnaissance. While conducting ISR, the submarine engages and neutralizes an enemy submarine and conducts mine counter warfare. The missile mission uses air, surface and land attack weapons to neutralize
SSG(X) Design – VT Team 3 Page 9 enemies. An enemy submarine is again neutralized and mine counter warfare is conducted. This mission also uses the ability of the submarine to replenish at a sea base. Day Table 3 – ISR Mission Mission scenario 1-15 Depart from CONUS on snorkel to area of hostilities 15-16 Proceed independently to within 10 nautical miles (nm) of enemy mainland 16-20 Conduct ISR 16 Avoid/neutralize enemy submarine attack 17 Conduct mine counter warfare. Launch counter mine AUVs that will detect and neutralize threat. 20-30 Continue ISR 28 Engage enemy patrol craft using Harpoon cruise missile 30 Return to sea base for rearming and refueling Table 4 - Missile Mission Day Mission scenario 1-15 Depart from home base submerged. Transit at snorkel depth, having batteries charged upon arrival. 15 Launch strike missiles against land target. Launch anti-air defense against an enemy ASW helicopter. 16 Kill incoming cruise missile salvo against CBG in cooperation with DDG. 17 Avoid/neutralize enemy submarine attack 18 Receive re-targeting information and perform cruise missile strike against updated targets. 19-20 Conduct mine counter warfare. Launch counter mine AUVs that will detect and neutralize threat. 15-30 Conduct EM, visual and radio reconnaissance 20 Replenish fuel and stores at sea base 25 Cooperatively, with Aegis unit, detect, engage, and kill incoming cruise missile salvo on CBG unit 26 Engage and destroy enemy surface ships using Harpoon cruise missiles 30 Return to sea base for rearming and refueling 2.5 Required Operational Capabilities To support the missions and mission scenarios described in Section 2.4, the capabilities listed in Table 5 are required. Each of these can be related to functional capabilities required in the ship design, and, if within the scope of the Concept Exploration design space, the ship’s ability to perform these functional capabilities is measured by explicit Measures of Performance (MOPs).
