Description

Mission Ship Self Def (Engage: Hard Kill)

This program element provides funding for the development of systems that fulfill a portion of the third phase of the Ship Self Defense: Engage Hard Kill. Development in this line will focus on hard kill capabilities in which missiles and other munitions are used to intercept incoming Anti-Ship Cruise Missiles (ASCM), as well as a Surface-to Surface Strike weapon system. System improvements are being addressed via Rolling Airframe Missile (RAM) (0167), NATO SEASPARROW Missile System (NSSMS) (0173), Over-The-Horizon (OTH) missile (2070), Afloat Counter-Unmanned Aerial Systems (C-UAS) (2077), and MK-15 Close-In Weapon System (CIWS) (9081).

Mission 5in Rolling Airframe Missile

The Rolling Airframe Missile (RAM) program is an international cooperative program with the government of the Federal Republic of Germany. The purpose of this program is to develop, test, and field a surface-to-air self-defense system consisting of both a missile and launcher. The latest fielded variant, the RAM Block 2B, defends against highly maneuverable Anti-Ship Missile (ASM) threats and emerging complex raid attacks utilizing an advanced seeker and missile-to-missile link while retaining all the proven capabilities of previous RAM variants (Block 0/1/1A/2/2A); accurate terminal guidance, proven lethality, and post-launch fire and forget capability. FY 2026 through FY 2030 efforts are as follows: 1) Complete integration of the latest RAM Guided Missile Weapon System (GMWS) into the Ship Self-Defense System (SSDS) Baseline (BL) 12 and Aegis Combat System. This will enable the fleet to deploy the full capability of the RAM Block 2B missile which entered production in FY 2023. 2) Continue the RAM "Performance Lab" which identifies improvements for incorporation through real-world events, trade studies, modelling and simulation, experiments, and test firings. 3) Continue the RAM Software Factory to provide end users with rapid missile software updates to address emerging threats. 4) Develop the Ship to Missile Uplink/Downlink (Stowed Kill Improvement Project (SKIP)). SKIP will utilize missile uplinks to provide the missile with continuous data from the combat system to improve mid-course and increase the probability of kill against complex raids. SKIP downlink will provide data back to the combat system to improve kill assessment fidelity. These system performance and efficiency improvements will be leveraged to decrease the required missiles per threat therefore increasing stowed kills per launcher. This capability will apply to both the MK 49 RAM launcher and the MK 15 SeaRAM launcher.

Mission NATO Sea Sparrow

This project encompasses eight (8) primary efforts to enhance ship self-defense: 1. ESSM System Integration and Test: Evolved SEASPARROW Missile (ESSM) Blk 1 and Block 2 is a cooperative effort among the 12 NATO SEASPARROW Project Consortium Nations including the U.S. to provide crucial battlespace defense and fire power against the fast, low altitude, highly maneuverable Anti-Ship Cruise Missile (ASCM) threat. Modifications were made to increase capacity by employing a four ESSM QuadPack in a single MK 41 Vertical Launch System (VLS) cell on DDG 51 Class Guided Missile Destroyers, CG 47 Class Guided Missile Cruisers, and the NATO SEASPARROW Surface Missile System (NSSMS) fielded onboard CVN 68 and CVN 78 Class Aircraft Carriers, LHD 1 and LHA 7 Class Multipurpose Amphibious Assault Ships. Major testing campaigns this year includes ESSM Block 2 Initial Operational Test and evaluation (IOT&E) Phase 2, which will continue the IOT&E test campaign, leading to the Full Rate Production Decision. Enterprise testing with SSDS BL 12 on the Self Defense Test Ship and lead ships CVN 79 and LHA 8. Both ESSM Block 1 and ESSM Block 2 will be used for Enterprise testing. 1.1 Block 2 Follow-on Test & Evaluation (FOT&E): The ESSM Blk 2 Milestone Decision Authority (MDA) mandated that ESSM Block 2 conduct FOT&E on Ship Self-Defense System (SSDS) platform and fully support DDG Flight III operational testing. There will be planning efforts to support US Combat Systems integration verification and flight testing including but not limited to: AEGIS Baselines 9 and 10, SSDS Baseline 12 (on SDTS CVN 79 and LHA 8), and FFG platform integration testing. All integration verification testing includes support with appropriate ESSM Block 2 Missile Simulator Unit (MSU) with operator support. 2. NATO SEASPARROW Technical Direction Agent (TDA): The MK 57 NATO SEASPARROW Surface Missile Systems (NSSMS) provides a rapid response, integrated, self-defense missile capability. The TDA provides systems engineering and technical support for the MK 9 Tracker-Illuminator System (TIS), and MK 29 Guided Missile Launching System (GMLS). The TDA is tasked with providing studies, analysis, prototyping, and evaluations of hardware and software improvements. This task encompasses requirements development and assessment, artifact and document reviews, technical meeting participation, test requirement development, analysis for test and system integration events, and post-test analysis. 3. ESSM Technology Roadmap Analysis & Prototyping support: The ESSM Block 2 Missile completed development in 2021, achieved Initial Operational Capability in December 2021 and transitioned to production and in-service phases. In order to achieve performance not realized during the execution of Engineering and Manufacturing Development (EMD), pace the threat, and remain a viable weapon system, the ESSM Block 2 and its supporting combat system components require continual improvements. This effort will perform studies to identify technology candidates, explore new manufacturing techniques and technologies, and determine applicability to the NATO SEASPARROW Project Office (NSPO) managed Combat System Elements for future hardware or software improvements to either the Consortium's combat systems or the missile, or both. Tasking includes development and maintenance of an ESSM System roadmap and support specific studies to determine candidate combat system and/or missile performance and manufacturing efficiency improvements. Computer simulation updates will be needed to support the performance studies for future improvements. 4. Other Development (Block 2 Obsolescence and Redesign, Combat System Test Bed (CSTB) and Digital Datalink): CSTB is the end-to-end integration of CS element models using Higher Level Architecture (HLA) to help assess a ship's ability to defend itself. CSTB is maximizing the use of tactical code-based models in conjunction with physics-based environmental models to represent at sea performance of ships and their combat systems. CSTB supports a system of systems modeling for multiple use cases including System Development, System Integration, Developmental Test (DT) or Operational Test (OT) for a variety of ships and weapon systems. This effort is to integrate ESSM Block 2 Tactical Simulation (ETS) model into the CSTB and Enterprise Testbed. This effort also includes improvements required to be made in ETS based on the studies exploring missile launcher and MK 9 Tracker Illuminator System (TIS) redesign in order to respond to obsolescence issues affecting ESSM systems on all CVN, LHA, and LHD class ships. 5. Evolved SEASPARROW Missile (ESSM) Block 2 Software Upgrades: The ESSM Block 2 Missile completed development in 2021, achieved IOC in December 2021 and transitioned to in-service. In order to pace the threat/new threat environments, maintain alignment with planned production technology refresh, and meet national requirements, the missile requires software improvements to provide performance updates and fixes and new capabilities. The software updates will be identified as a result of Initial Operational Test and Evaluation (IOT&E) phase 2 and during Runs for the Record (RfR) that will be completed in support of Full Operational Capability (FOC), from performance improvements studies, identified software trouble reports, and during Final Operational Test and Evaluation (FOT&E) flight test results and as a result of new hardware and combat system changes. These software changes form the first opportunity to improve the baseline ESSM Block 2 missile and will be delivered as software updates employing agile software management principles, which will allow for correction of deficiencies identified through Initial Operational Test and Evaluation and support the completion of FOT&E objectives. 6. C-Band Telemetry Upgrade: Director Operational Test and Evaluation (DOT&E) directed operational testing in Aegis Capability Baseline (ACB)-20 requires multiple missiles in flight simultaneously to assess stream raids by threat systems. Current SM-6 and ESSM Block 2 Telemeters operate in the S-band where Radio Frequency (RF) bandwidths are limited for Telemetry (TM) data collection on the range. The current spectrum allocation and range infrastructure does not support TM collection for the number of missiles simultaneously in flight required to support ACB 20 TEMP (Test and Evaluation Master Plan) on range. The new requirement is due to the large number of missiles to support planned testing. The weapons and range are required to move telemetry into the C-Band where bandwidth exists to support required TM collections. 7. NATO SEASPARROW Tracker-Illuminator System (TIS) Development: The MK 57 NATO SEASPARROW Surface Missile System (NSSMS) supports the SEASPARROW missile semi-active missile requirement with a Continuous Wave Tracking Illuminator (CWTI) as the heart of the MK 9 Tracker-Illuminator System (TIS). The MK 9 TIS provides fire control tracking data to the SSDS combat system, including against high elevation angle threats. The OT-234/S Transmitter Group eliminates obsolescence issues and increases the Radio Frequency (RF) power output to provide improved tracking, with uplink, performance, and higher ESSM probability of guidance (PG) on low RADAR Cross Section (RCS) threats. Additionally, a replacement of 1960's United States Air Force (USAF) Radar Test Set (RTS) adapted for the United States Navy (USN) will be required to fulfill maintenance requirements and enhance additional frequency selections and ensure post-launch RF missile support for noise and uplink requirements. 8. Adaptable Deck Launcher (ADL) (formerly Next Generation Launching System (NGLS): The purpose of the ADL effort is to develop, qualify, test, and integrate a replacement to the 50+ year old legacy MK 29 Guided Missile Launching System (GMLS) for large deck, capital warships including CVNs, LHAs, and LHDs. ADL will double ESSM capacity over the current MK 29 GMLS while maintaining current shipboard locations. The new launching system will allow significantly more flexibility for ESSM Block 1 and 2 in different loadout configurations with available inventory. This replacement will improve environmental protection for Guided Missile Assemblies (GMA) (reducing corrosion), reduce manning requirements for loading/unloading operations, mitigates long term supportability issues, addresses obsolescence, reduce the life cycle costs, and reduce the cost and time for ESSM in-service refurbishment or re-certification. The ADL replacement contains design margin to allow for ESSM evolutionary growth within the MK25 canister. The MK 29 GMLS capacity is limited for ESSM Block 2 deployment.

Mission OTH Missile

Over-The-Horizon (OTH) Missile funds competitive acquisition, testing, integrating and fielding of a modern, technologically mature Over-the-Horizon Missile Launch System (OTH-MLS) surface to surface missile capability will be installed onto commissioned and in-production Littoral Combat Ship Variants/Frigate(LCS/FFG)beginning FY 2019.

Mission Afloat C-UAS

Afloat Counter Unmanned Aerial Systems (C-UAS) was established to meet an urgent operational need and funds the acquisition, testing, integration, and fielding of prototype C-UAS's to provide a lower cost defense in-depth solution to negate the UAS threats. The FY 2026 discretionary $39.407 million will fund long lead items for the C-UAS systems. Once additional funds are received, the Navy will accelerate new capability integration and fielding to the Fleet.

Mission Phalanx CIWS SEARAM

The MK 15 MOD 40 Close in Weapon System (CIWS) RAM Defense Capability (CRDC) configuration is fielded aboard Nimitz Class Carriers (CVN). It is a fast reaction, rapid fire, computer-controlled radar system that employs the Rolling Airframe Missile (RAM) as an effector for Anti-Ship Missile (ASM) defense. The MK 15 MOD 40 CIWS (CRDC) configuration was fielded in FY 2020, limited to the RAM BLK 2 missile variant. The purpose of this project is to develop and integrate the latest RAM missile variant (BLK 2B) into the MK 15 MOD 40 baseline. The RAM Block 2B missile defends against highly maneuverable Anti-Ship Cruise Missile (ASCM) threats and emerging complex raid attacks utilizing an advanced infrared (IR) seeker and Missile-to-Missile Link (MML) while maintaining all the proven capabilities of previous RAM variants (BLK 2): accurate terminal guidance, proven lethality, and post-launch fire and forget capability. Without this effort the Nimitz class carriers will be unable to utilize the latest and most capable RAM Block 2B missile which entered production in FY 2023.
