NATO Sea Sparrow
Abstract
This project encompasses ten (10) primary efforts to enhance ship self-defense: 1. Evolved SEASPARROW Missile (ESSM) Blk 1 is a cooperative effort among nine (9) NATO SEASPARROW Nations and 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 both the MK 41 Vertical Launch System (VLS) to fire from a single cell with 4 ESSM (QuadPack) and the NATO SEASPARROW Surface Missile System (NSSMS), fielding ESSM Blk 1 onboard CVN 68 (Aircraft Carrier), LHD 1 (Multipurpose Amphibious Assault Ship), LHA 7 (Multipurpose Amphibious Assault Ship), CG 47 (Guided Missile Cruiser), and DDG 51 (Guided Missile Destroyer) class ships. ESSM Blk 1 integration efforts continue to bring the capability to CVN 78 and DDG 1000. 2. Blk 2 Follow-on Test & Evaluation (FOT&E): The ESSM Blk 2 Milestone Decision Authority mandated that ESSM Blk 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 testing including but not limited to: Aegis Baseline 9 and 10 integration, SSDS integration, FFG platform integration testing as required. This includes support with appropriate ESSM Blk 2 Missile Simulator Unit (MSU) with operator support. 3. 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 Technical Direction Agent (TDA) is tasked with providing systems engineering and technical support for the MK 9 Tracker Illuminator System (TIS), and MK 29 Guided Missile Launching System (GMLS). The Combat System (CS) TDA is tasked with providing an Analysis of Alternatives (AoA), in the form of studies, analysis, and evaluations of hardware and software improvements. This task encompasses requirements development, and assessment, artifact and document reviews, technical meetings, and test requirement development, participation in test and system integration events, and post test analysis. RDT&E funding is necessary to complete AoA activities and develop recommendations, based on data, for improvements to the MK 9 TIS and MK 29 GMLS. 4. ESSM Technology Roadmap & Studies: The ESSM Blk 2 Missile completed development in 2021, achieved IOC in December 2021 and transitioned to in-service. In order to achieve performance not realized during the execution of Engineering and Manufacturing Development (E&MD), pace the threat, and remain a viable weapon system, the missile and its supporting combat system components will require improvements. This effort will perform studies to identify technology candidates, find new manufacturing techniques, 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. RDT&E funding represented will develop and maintain 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. 5. Other Development (Blk 2 Obsolescence and Redesign, CSTB and Digital Datalink): Test Bed is the end-to-end integration of Combat System (CS) element models using Higher Level Architecture (HLA) to help assess a ship's ability to defend itself. Test Bed 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. The goal is to develop 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 Combat Systems Testbed and Enterprise Testbed. This effort also includes improvements needing 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. 6. Evolved SEASPARROW Missile (ESSM) Blk 2 Software Upgrades: The ESSM Blk 2 Missile completed development in 2021, achieved IOC in December 2021 and transitioned to in-service. In order to pace the threat and remain a viable weapon, the missile requires software improvements. This effort will provide the performance updates and fixes to the ESSM Block 2 missile software. The software updates will be identified as a result of the Initial Operational Test and Evaluation (IOT&E) phase and during Runs for the Record (RfR) that will be completed in support of IOC, from performance improvements studies, from identified software issues, during FOT &E flight test results and as a result of new hardware and combat system changes. These changes will form the first opportunity to improve the baseline ESSM Block 2 missile, and are intended to represent an approximately annual software update employing agile software management principles, which will allow for correction of deficiencies identified through Initial Operational Test and Evaluation, and support the completion of Follow On Operational Test and Evaluation objectives. 7. 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 Evolved SEASPARROW Missile (ESSM) Block 2 Telemeters operate in the S-band where Radio Frequency (RF) bandwidths are limited for Telemetry (TM) collection on the range. The current spectrum allocation and range infrastructure only supports TM collections for 3 active missiles in flight on the range at one time. 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. Engineering has already certified that this is achievable. 8. MK 9 Continuous Wave Tracking Illuminator (CWTI) (Transmitter) Replacement: The MK 57 NATO SEASPARROW Surface Missile System (NSSMS) supports the SPARROW missile family with Semi-Active illumination in the form of Continuous Wave Tracking Illuminator (CWTI). The CWTI enables the MK 9 Tracker-Illuminator System (TIS) to support self-defense mission requirements and paces emerging threats. The MK 9 TIS CWTI replacement eliminates obsolescence issues and increases the Radio Frequency (RF) power output to provide improved tracking, with uplink, performance, and higher Evolved SEASPARROW Missile (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. 9. Next Generation Tracker-Illuminator System (TIS): An upgrade is required to existing ship's infrastructure to provide Semi-Active (SAX) illumination source that improves Evolved SEASP ARROW Missile (ESSM) Block 2 probability of guidance (PG) when using Transition Section Guidance (TSG) Mode 0, 3 (current), or 5 (future). Additionally, an upgraded MK 9 TIS will improve Combat System probability of raid annihilation (PRA) for TSG Modes O and 5 (future). The receiver and tracking elements have reached the limits of their ability to support system requirements and deficiencies have been noted in Follow-on Operational Test and Evaluation (FOT&E) out-briefs. This effort will develop (as required), qualify, test, and integrate modernized technology (equipment/ components) as part of the MK 9 TIS (e.g., Transmitter Group, Antenna, and Signal Processor). 10. Next Generation Launching System: Develop, qualify, test, and integrate an upgrade/replacement to the legacy MK 29 Guided Missile Launching System (GMLS). This upgrade/replacement improves environmental protection for Guided Missile Assemblies (GMA) (reducing corrosion), Grade A Near Miss Shock (NMS) compliance, reduces manning requirements for loading/unloading operations, mitigates long term supportability issues, addresses obsolescence, reduces the life cycle cost for operating and maintaining the MK 132 Launcher, and reduces the cost and time for Evolved SEASPARROW Missile (ESSM) in-service refurbishment, or re-certification. This upgrade/replacement contains design margin to allow for growth, where the MK 132 Guided Missile Launcher is maximized today precluding ESSM Block 2 deployment.
