HPM System

Intelligence Summary: HPM System

Node Identity: HPM System is a project categorized under "National Project" in the japan intelligence graph. High-Power Microwave phased-array radiation weapon using active electronically scanned antenna to disable UAV swarms, FY2022-FY2026 program with 86 billion yen budget.

Research Evidence: The following findings from 6 research documents reference this entity:

1. Yossi Margalit, VP and Managing Director of C-UAS & Low Altitude Air & Missile Defense Systems at Rafael, stated at the UVID conference in Tel Aviv (November 2025) that HPM systems are "the holy grail of interceptors" and "the next level up" of C-UAS technology, with "capabilities never seen before" following the operational use of laser interception technology.
2. Evidence: At the November 2024 Zhuhai Air Show, the PLA showcased Hurricane 2000, Hurricane 3000, and FK-4000 HPM systems (2-3 km range, counter-drone).
3. Japan also operates a comprehensive DEW portfolio: 10 kW vehicle-mounted laser (MHI), 100 kW-class containerized laser (KHI, tested on JS Asuka), phased-array HPM system (FY2022-FY2026, ~$63M), and the world's most advanced ship-based electromagnetic railgun (2,297 m/s, first successful target vessel strike at sea, June-July 2025).
4. The DEW Revolution is Here; the Plasma Weapon Revolution is Not** The operational deployment of HEL systems (Israel, South Korea) and HPM systems (China, Russia) represents a genuine revolution in warfare — the transition from kinetic to directed energy engagement.
5. Confidence: ESTABLISHED --- ## L4: DRDO Directed Energy Weapons — Mk-II(A), DURGA-II, and HPM Systems ### Finding: DRDO has achieved significant milestones in directed energy weapons (DEW), including successful testing of a 30 kW laser DEW (Mk-II(A)) in April 2025 that destroyed drones and surveillance sensors at ranges >3 km.
6. The HPM system at 450 MW peak power is particularly significant as it represents a plasma-based microwave weapon capable of electronic kill effects.
7. While these are laser and microwave systems rather than "plasma weapons" in the classical sense, the HPM system involves plasma physics (microwave-plasma interactions, relativistic electron beam generation).
8. • FOI-R--0362--SE (January 2002) "Några frågor rörande antenner för HPM-tillämpningar" (Some issues concerning antennas for HPM) — estimates antenna performance for mobile/missile-borne HPM systems, including vircator-based microwave generation in vacuum and impulse radiating antennas (IRA); part of a pre-study to decide whether to build an HPM warhead demonstrator.

Strategic Relevance: HPM System is a tracked entity within the japan network. With 3 documented connections to other entities, this node plays a supporting role in the network topology.

Network Linkage: This entity maintains 3 documented connections in the intelligence network: HPM System developer ATLA; HPM System subject US-Japan HPM PA; ATLA developer HPM System.
