The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Description
Description — Close-In Wpns Sys (CIWS) Mods
Phalanx Close-In Weapon System (CIWS) is an autonomous combat system that searches, detects, tracks (radar and electro-optic), and engages threats with a 20mm Gatling gun capable of firing 4,500 tungsten penetrator rounds per minute. Integral to ship self-defense and the anti-air warfare "defense-in-depth" concept, CIWS provides terminal defense against anti-ship missiles and high-speed aircraft penetrating other fleet defenses. Phalanx CIWS can operate autonomously or be integrated with a ship's combat system. The CIWS Block 1B configuration provides further defense against asymmetric threats such as small, fast surface craft, low slow-flying fixed and rotary-winged aircraft and unmanned aerial vehicles through the addition of an integrated Forward-Looking Infra-Red (FLIR) sensor. Block 1B also incorporates an Optimized Gun Barrel (OGB) for tighter ordnance dispersion. Enhanced Lethality Cartridges (ELC) can be used with the OGB for improved target penetration. The MK 15 MOD 40 CIWS RAM Defense Capability (CRDC) configuration is fielded aboard select Nimitz Class Carriers (CVN). It is a fast reaction, rapid fire, computer-controlled radar system that employs the Rolling Airframe Missiles (RAM) as an effector for Anti-Ship Missile (ASM) defense. The latest RAM missile variant (Block 2B) 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: accurate terminal guidance, proven lethality, and post-launch fire and forget capability. [P5 / DT001 CIWS BLOCK 1B]: This budget provides for hardware procurements to address safety, obsolescence, and reliability improvements. There are 237 U.S. (USN/USCG) shipboard systems, 8 trainers, and 3 Engineering Development Module (EDM)/Periodic Conformance Inspection (PCI) mounts. [P5 / DT001 CIWS (CRDC) MK 15 MOD 40]: Funding supports MK 15 MOD 40 hardware procurement and installation of Ordnance Alterations (ORDALT) to address safety, obsolescence, and reliability.
Justification
Justification — Close-In Wpns Sys (CIWS) Mods
The FY 2025 to FY 2026 funding increase procures corrective action and reliability ORDALTs for the MK 15 MOD 40 CRDC sensor. It also continues 10 procurements for the Gun Ammo Handling System (GAHS) and Electronic Gun Drive (E-Gun) ORDALTs. The GAHS ORDALT improves system operational availability and reliability by introducing a modified design with improved materials for components that are prone to fatigue and causing ammo handling jams. The E-Gun ORDALT replaces the pneumatic gun drive components with an electric drive system providing an increased number of engagements thru better control of fire rates and a reduced rate of fire variability. It also reduces maintenance hours, improves Built-In Test (BIT) and troubleshooting, increases reliability by eliminating high failure pneumatic components and reduces gun jams. The CRDC reliability ORDALTs increase reliability of the CRDC sensor. The sensor is the primary reliability degrader of the system and corrective actions are necessary to achieve the systems required operational availability. CRDC corrective action and reliability improvement kit procurements (two per hull) for the Linear Oscillator (LO) and Transformer Rectifier Unit (TRU) begin in FY2026.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions

GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not CIWS Mods. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
