Description
Description — DDG Mod
The DDG Modernization (DDG MOD) Program is required to upgrade the in-service Flight I, II, and IIA DDG-51 Class ships in order to keep the DDG Class relevant and operational. The DDG MOD Program is composed of a series of improvements in both Hull, Mechanical, and Electrical (HM&E) and Combat Systems. Modernization changes are aligned with New Construction design to increase commonality and capitalize on Economic Order Quantities across all programs. In FY26, DDG MOD continues DDG MOD 2.0, the next phase of combat capability enhancements bringing Integrated Air and Missile Defense (IAMD) capability to the DDG 51 Class. In addition to the DDG MOD 1.0 HM&E and Combat Systems upgrades, DDG MOD 2.0 ships will be equipped with SLQ-32(V)7 Surface Electronic Warfare Improvement Program (SEWIP) Block III (funded in 0204228N OPN 2312 AN/SLQ-32), SPY-6(V)4 Air and Missile Defense Radar (AMDR) with updated AEGIS Baseline 10M / Ballistic Missile Defense (BMD) 6M, and High Efficiency Super-Capacity (HES-C) Chillers. DDG MOD 2.0 upgrades are planned for each ship's mid-life availability. PB26 reflects updated ship schedules and resourcing as summarized below: DDG 97 (USS HALSEY) resourcing in FY25 vice FY24 DDG 98 (USS FORREST SHERMAN) resourcing in FY26 vice FY25 DDG 101 (USS GRIDLEY) availability shifted from FY26 to a future FY DDG 102 (USS SAMPSON) availability shifted from a future FY to FY26 DDG 109 FY25 procurements and future FY availability deferred Prior year procurements from availability deferrals continue to support installations on DDG 102 in FY26 and DDG 101 in a future FY. Incorporation of updated private sector man-day rates. Installation quantities starting in FY26 are as follows: HM&E Modernization: - 1/0/0/0/0 DDG MOD 1.0: 1/0/0/0/0 DDG MOD 1.5: 2/1/0/0/0 DDG MOD DMP2: 1/1/2/0/0 DDG MOD 2.0: 0/0/0/2/2 The definitions for DDG MOD installations are listed below: HM&E Modernization: HM&E DDG MOD 1.0: HM&E + C/S DDG MOD 1.5: HM&E + C/S + SLQ-32(V)7 (SLQ-32(V)7 is funded outside of DDG MOD 2.0) DDG MOD DMP2: SPY-6(V)4 + HES-C (these hulls have already received DDG MOD 1.5 in a previous availability) DDG MOD 2.0: HM&E + C/S + SLQ-32(V)7 + SPY-6(V)4 + HES-C HM&E modernization is comprised of Commercial Off the Shelf (COTS) technologies for Ship Control and Engineering Plant Control Systems. New systems provide increased situational awareness, reduce manpower workloads, and address reliability and obsolescence challenges with legacy systems. C/S modernization upgrades the Aegis Weapon Systems (AWS). The upgrades enable the DDG-51 Class to conduct Ballistic Missile Defense simultaneously while conducting Air Defense within its assigned theatre. Upgrades allow for the use of AEGIS Open Architecture (AOA) replacing legacy signal processors with a Multi-Mission Signal Processor (MMSP) for DDG MOD 1.0 ships. For DDG MOD 1.5, DMP2 and DDG MOD 2.0 ships, C/S modernization establishes the foundation for upgrading the DDG-51 Class from the SPY-1 radar array to the SPY-6(V)4 solid-state radar, enabling the DDG-51 Class to remain tactically competitive against emerging threats. DDG MOD installations traditionally utilize a Firm Fixed Price Contracting Strategy for both the East and West Coasts of the United States. Installation costs require multiple years of funding per ship to support Ship Checks (S/C), Ship Installation Drawing (SID) development, Long Lead Time Material purchase, and physical installation. Installation costs are budgeted based on the ship's homeport man-day rates as promulgated by the Navy.
