Iranian drones range from backpack-sized systems a bit over 2 meters long to large aircraft‑style drones around 10–11 meters, with the famous Shahed attack drones sitting in the small‑airplane/heavy-moped size range.

Quick Scoop: How big are Iranian drones?

Think of Iran’s drone fleet as a whole toolbox: some are “flying mopeds,” others are closer to small planes.

1. The well‑known Shahed “kamikaze” drones

  • Shahed‑131
    • Length: about 2.6 m (≈ 8.5 ft).
* Wingspan: about 2.2 m (≈ 7.2 ft).
* Rough mental image: a person‑sized flying wing, small enough to move by truck or small launcher.
  • Shahed‑136 (also known as Geran‑2 in Russian service)
    • Length: about 3.5 m (≈ 11.5 ft).
* Wingspan: about 2.5 m (≈ 8.2 ft).
* Warhead: roughly 40 kg explosive payload.
* Rough mental image: about as long as a compact car, but with short stubby wings.

If you’ve seen videos from Ukraine or recent Middle East strikes, the loud, slow, buzzing drones hitting buildings are usually this Shahed‑136 class.

2. Very small suicide drones

  • Meraj‑521 (one of the smallest publicly known)
    • Designed as a small “suicide” drone.
* Carries only about 3 kg of explosives, indicating a compact body, closer to a large hobby/commercial drone in overall footprint.

These are closer to man‑portable or vehicle‑portable systems, not huge aircraft.

3. Larger combat and reconnaissance drones

Iran also fields much larger drones that look more like traditional military UAVs.

  • Shahed‑149 (heavy combat/surveillance drone)
    • Described as a large drone with up to 500 kg payload and about 2,000 km range, putting it in the same general size category as well‑known MALE (medium‑altitude long‑endurance) drones like the U.S. MQ‑9 Reaper.
* Exact dimensions aren’t always given, but this class typically runs on the order of 10–11 m length with a broad wingspan, i.e., small‑aircraft sized (the public data emphasizes payload and range more than exact meters).
  • Mohajer series
    • Multi‑role drones used for surveillance and strike.
* Earlier Mohajer types are closer to small light aircraft; newer ones (like Mohajer‑10) carry up to about 300 kg payload and have roughly 2,000 km radius, again implying a sizable airframe in the multi‑meter, small‑plane range.

Shahed‑149 Heavy UAV; up to 500 kg payload, ~2,000 km rangeLong‑range combat/surveillance

5. Why “how big” matters in 2026 news

In recent months, the size and range of Iranian drones have been central to coverage of strikes from Ukraine to the Gulf region. The small, cheap Shahed‑136 class is big enough to carry a serious warhead but small and simple enough to be mass‑produced and launched in swarms, which is exactly why you’re seeing them all over the latest news and forum discussions about changing warfare.

TL;DR: Most talked‑about Iranian kamikaze drones (Shahed‑136) are roughly 3.5 m long with a 2.5 m wingspan—about compact‑car length—while the overall fleet runs from small backpackable systems up to large, small‑aircraft‑sized combat drones.
