The U.S. military faces a well-documented challenge in air and missile defense: insufficient magazine depth, slow production rates, and extremely high per-shot costs. This problem becomes more acute under the emerging “distributed” operational concept — smaller, more numerous autonomous or lightly manned platforms, forward-deployed Marine units, loyal wingman/CCA drones, and unmanned surface vessels. These assets must often operate with limited escort and defend themselves against saturation attacks.
Current systems rely heavily on expensive missiles, creating an unfavorable cost-exchange ratio against low-cost drones and missiles. Recent events in the Red Sea, Ukraine, and elsewhere highlight this vulnerability.
Existing Capability: ExLS + CAMM
One promising development is the Lockheed Martin Mk 41 ExLS (Extended Length System) 3-round VLS module paired with the MBDA CAMM (Common Anti-Air Modular Missile). Unlike standard hot-launch Mk 41 cells, ExLS uses cold-launch (gas generator ejection), which significantly reduces weight and complexity by eliminating heavy exhaust plenums and cooling systems. This makes it suitable for smaller vessels and unmanned platforms.
CAMM has demonstrated good performance in tests, including against simulated supersonic anti-ship threats, and can be quad-packed. A single 3-round ExLS module provides 12 missiles. Sweden has selected the system for Visby-class corvettes.
However, limitations remain:
Anduril appears well-positioned to develop a complementary or lower-tier missile that could expand the ExLS ecosystem and address cost/asymmetry issues.
Phase 1 Concept (IR/Laser Seeker Variant)
Additional Applications
Phase 2 Concept (Active Radar Variant)With an established chassis, Anduril could develop its own GaN AESA radar seeker. This would create a far cheaper alternative to CAMM while providing all-weather capability and better performance in clutter. The same airframe could support both seeker types, enabling a flexible family of missiles.
This radar-guided variant would:
This concept builds on existing programs and technologies rather than starting from scratch, which improves feasibility.

However, limitations remain:
- CAMM costs approximately $250,000 per round — still expensive for engaging low-cost drones.
- Performance against small, low-altitude surface drones (e.g., Sea Baby types) in clutter may be limited.
- European production capacity could constrain availability during high-intensity conflict.
Anduril appears well-positioned to develop a complementary or lower-tier missile that could expand the ExLS ecosystem and address cost/asymmetry issues.
Phase 1 Concept (IR/Laser Seeker Variant)
- Develop a new airframe using rapid, low-cost manufacturing techniques demonstrated in the Barracuda program.
- Design for cold-launch compatibility with ExLS cells (sealed canister with gas generator).
- Adopt the existing IIR/laser-designator seeker from the APKWS Hydra rocket program (already in high-rate production).
- Leverage Adranos (Anduril subsidiary) rocket motor technology with ALITEC propellant for a target range of 20–25 km.
- Include an air-launched variant for fighters, attack helicopters, Reapers, and CCA loyal wingman drones.
Additional Applications
- Containerized ExLS: Four modules configured as a standalone, transportable VLS “air defense in a box” within a standard 20' ISO container envelope and erectable launcher. This could be rapidly deployed on land or at sea, linked to a suitable radar for immediate capability.
- Air-launched version: Potentially carriage-compatible with F-35B, CCA drones, and helicopters for multi-role (anti-drone, anti-tank, limited air-to-air) capability at lower cost than existing munitions.
Phase 2 Concept (Active Radar Variant)With an established chassis, Anduril could develop its own GaN AESA radar seeker. This would create a far cheaper alternative to CAMM while providing all-weather capability and better performance in clutter. The same airframe could support both seeker types, enabling a flexible family of missiles.
This radar-guided variant would:
- Strengthen the ExLS high/low mix and make the overall system more attractive.
- Create technology synergies across Anduril’s portfolio (Barracuda, Roadrunner, Ghost-X, Altius, etc.).
Strategic Implications
A family of missiles in this weight/range class (≈200 lb, 20–25 km) could significantly improve magazine depth and cost-effectiveness for distributed operations. It would be particularly valuable for export customers (e.g., Taiwan, smaller navies) seeking affordable asymmetric defense.This concept builds on existing programs and technologies rather than starting from scratch, which improves feasibility.
