HENSOLDT MSSR 2000 I: Military IFF Radar in 55+ Countries and the Mode 5 Upgrade
MSSR 2000 I (Monopulse Secondary Surveillance Radar 2000 Identification) is HENSOLDT’s military IFF and secondary surveillance radar, deployed in over 55 countries. It answers the most critical question in modern air combat: is that radar return a friend, a neutral, or an enemy?
Why Monopulse?
Classical rotating-beam radars determine angular position by analyzing how long a target stays in the beam — a slow, imprecise method. Monopulse technology fires multiple simultaneous beam lobes and calculates the exact angular position from a single radar pulse. The result: far faster and more precise target location — critical when many aircraft are in the same airspace simultaneously.
Technical Specifications
- Frequency band: L-band (1–2 GHz) — the IFF/SSR standard band
- Mode compatibility: Mode 1/2/3/A/C/S and Mode 5 (modern NATO IFF standard)
- Installed countries: 55+
- Integration: co-mounted with primary radars (ASR-NG, TRML-4D)
- Range: 450+ km
Mode 5: The NATO Upgrade Wave
NATO is completing its transition from Mode 4 to Mode 5 IFF — an encrypted, GPS-integrated protocol far harder to spoof than its predecessor. Every country that has fielded MSSR 2000 I must upgrade to Mode 5, generating a major service and upgrade revenue wave for HENSOLDT across its installed base of 55+ nations.
