US-Norwegian startup Heaviside launches Tyr loitering munition

TL;DR: Heaviside, a US‑Norwegian drone startup, unveiled the 15‑lb Tyr loitering munition, leveraging a close partnership with Norway’s Nammo for anti‑tank warheads and rapid testing.

The Details

Heaviside announced its entry into the low‑cost expendable‑drone market with the Tyr loitering munition. While corporate headquarters and most staff are in Los Angeles, engineering, development, and flight testing occur at a facility in Norway adjacent to Nammo, Heaviside’s primary partner. Nammo supplies the anti‑tank warhead (derived from the M72 LAW series) and provides a test range for live‑explosive trials, enabling same‑day build‑and‑test cycles. Tyr weighs roughly 15 lb, is soldier‑portable, and carries a warhead capable of defeating main‑battle‑tank armor such as the Russian T‑72/T‑80. The company emphasizes its veteran engineering team and rapid development cycle as differentiators, though pricing was not disclosed.

Watch For

  • Confirmation of unit cost and production scaling plans.
  • Procurement interest or contracts from NATO, U.S. or allied armed forces.
  • Further performance data, especially against hardened targets and in adverse weather conditions.
