Distributed Mass MANPADS — Riflemen Union, Territorial Defense, and Critical Infrastructure

Executive Summary

After the 39-day Iran war of June to September 2025, Western air-defense factories cannot produce enough Patriot or SAMP/T missiles to cover Lithuania any time soon. Production through 2028 is committed to rebuilding Gulf and US theatre stocks; the next French SAMP/T NG batteries are queued out to 2030. The one part of the supply chain still producible at scale is the family of short-range, shoulder-fired missiles (known as MANPADS, for Man-Portable Air Defence Systems): the French Mistral 3, the Polish Piorun, the American Stinger, the British Starstreak, and the Swedish tripod-mounted RBS 70 NG. Ukraine's air-defence experience from 2022 to 2025 showed that thousands of these missiles, distributed widely, force Russian helicopters and low-flying jets out of the airspace they need to support a ground attack. Lithuania's roughly 200 to 400 launchers today are not enough; the Lithuanian Riflemen Union, the volunteer reservist organisation under the Ministry of Defence, and territorial defence battalions have almost no organic air-defence capability; and major sites like the Klaipėda LNG terminal, the Vilnius electricity grid ring, and Šiauliai air base have no dedicated missile cover. The project recommends that the Ministry of Defence stand up a working group in 2026 to study a four-tier procurement of about 2,100 launchers, all held in military armouries under the regular military chain of command. Riflemen Union members would serve as spotters and loaders alongside trained reservist shooters, never as home-issued trigger-pullers; this is the discipline needed to avoid repeating the Stinger-to-Afghanistan diversion of the 1980s, where about 600 of 2,300 missiles were never recovered. Honest hardware cost at current prices is around 2.3 billion euros for a full 3,000-launcher mix and roughly 1.6 to 1.9 billion euros for the recommended 2,100-launcher version, phased over six to eight years. The exact mix of suppliers, the role of the Riflemen Union, and the schedule should be set by Lithuanian defence planners, not by this brief.

The Problem

A Russian air campaign against Lithuania would not look like the high-altitude bomber raids of the 1991 Gulf War. It would look like Ukraine since 2022: Ka-52 and Mi-28 attack helicopters flying low across the Belarus and Kaliningrad borders towards the Suwałki gap and Vilnius; Su-25 and Su-34 jets dropping glide bombs from 40 kilometres away; waves of cheap Iranian-design Shahed-136 drones (called Geran-2 in Russian service) cruising at 60 to 4,000 metres before diving onto targets; Lancet-3 loitering munitions hunting radars; and the new jet-powered Geran-3 (Telefly JT80 turbojet, per Ukrainian intelligence cited in united24media.com) cruising at 9,000 metres. The 39-day Iran war confirmed that even allied countries with quality interceptors run out of missiles within weeks under saturation attack: Saudi Arabia and Israel both burned through their forward-deployed Patriot stocks. Lithuania's four to six NASAMS batteries cannot solve the low-altitude, high-volume part of this threat.

Lithuania holds an estimated 200 to 400 shoulder-fired air-defence missiles, mostly Stinger and the older Polish Grom, concentrated in the Air Force's Air Defence Battalion. The Lithuanian Riflemen Union (Šaulių Sąjunga) has about 17,000 to 18,000 members — including roughly 6,000 cadets under 18 — and effectively zero organic air-defence capability. Territorial defence battalions have patchy coverage. Major sites — the Klaipėda LNG terminal, the Vilnius substations, the Mažeikiai refinery, the Kruonis pumped-storage station, the Šiauliai NATO air-policing hub — rely on facility guards and police, not missile cover. There is no national doctrine document for distributed shoulder-fired air defence. Crucially, no missile in this category can reach the Geran-3 jet drone at its 9,000-metre cruise altitude; engagement is only possible in the final dive, a window of seconds.

Without action: Without distributed mass: Russian helicopter assault into the Suwałki corridor and Vilnius approaches faces only NASAMS engagement at 25 kilometres or more, leaving a permissive low-altitude lane to the objective; Shahed terminal dives onto Klaipėda LNG and the Vilnius grid lose the 40 to 60 percent intercept rate Ukrainian operators have demonstrated; the citizen-soldier core of Lithuanian total defence stays infantry-only, missing the leverage that turns territorial mass into air denial; and every quarter of procurement delay pushes initial deliveries out by another two quarters as Gulf and Indo-Pacific demand absorbs the available production.
