1. HIMARS, short for High Mobility Artillery Rocket System, is a lightweight, highly mobile long-range rocket artillery system developed by Lockheed Martin.Main Features:1. Platform: Based on the U.S. military’s M1140 five-ton truck chassis, it can be airlifted by transport aircraft such as the C-130, providing excellent mobility.2. Weapon System: Equipped with a rotating launch device, it can load: 6 rounds of 227mm caliber rockets (such as M31 GMLRS, range 70–90km); or 1 ATACMS tactical ballistic missile (range up to 300km).3. Operation: Operated by 3 personnel, but the actual launch process can be completed by 1 person.4. Fire Control System: Highly automated, allowing for rapid loading, targeting, and launching.Operational Applications:1. Long-range precision strikes: Primarily relies on GPS-guided rockets (GMLRS), demonstrating outstanding performance in the Russia-Ukraine conflict.2. Rapid mobility: Capable of “shoot and scoot,” reducing the risk of counterattacks from the enemy.3. Flexible ammunition configuration: In the future, it can launch the PrSM precision strike missile, with a projected range exceeding 500km.

2. Da Mao claims that these fragments were from M30 GMLRS rockets launched by HIMARS or M270. This rocket has a cluster warhead containing M85 DPICM submunitions. M30 is the first guided rocket used for the M270 MLRS, equipped with inertial and GPS receivers.
3. Highlights of the Circuit Board Design and Process1. At the circuit level, power conversion, processor/ASIC, storage, and interface circuits are integrated into a compact layout. The PCB is coated with conformal coating and encapsulated in a metal shell to ensure high shock resistance and electromagnetic protection.
2. The RF section is equipped with a RAKON TSX crystal oscillator (10.949297MHz), custom filters, and power amplifier chips, indicating its role in high-frequency transceiver tasks related to GPS/navigation.
3. In terms of connectivity, flexible circuits (FPC) are used for coupling between the main control unit and the laser gyroscope, which not only saves space but also enhances reliability in high-vibration environments.
