While both are one-way systems, the Shahed-136's advanced options allow for better performance against moving targets. Analysts note that in jammed environments, such as those in Ukraine, the Shahed-136 still achieves hits, outperforming the Samad-3's simpler setup.
Shahed-136 is superior for its more robust guidance, providing greater accuracy in modern electronic warfare contexts.
Cost and Affordability
At an estimated $30,000 per unit, the Samad-3 is affordable for Houthi forces, allowing mass launches as in the 2019 strikes, but its production is likely limited. The Shahed-136, priced between $20,000 and $50,000, benefits from Iran's mass production, with reports of hundreds manufactured monthly, as used in Ukraine. This cost structure creates a favorable exchange ratio, where defenders must spend far more to intercept. In conflicts, the Shahed-136's economics enable swarm tactics, while the Samad-3's slightly higher cost per unit restricts large-scale deployments without external support.
Shahed-136 is preferable for its lower cost and scalability, making it ideal for sustained, high-volume operations.
Combat Performance
The Samad-3 proved its combat value in the 2019 Abqaiq attack, disrupting global oil supplies with a small warhead, but its slow speed makes it easy to intercept if detected early. Shahed-136 has seen extensive use, with Russia launching thousands in Ukraine and Iran using over 170 in the 2024 Israel attack, many intercepted but still overwhelming defenses. Both share weaknesses like vulnerability to MANPADS, yet the Shahed-136's ability to operate in swarms has led to more frequent successes. In real terms, the Shahed-136's deployment record shows higher adaptability in varied theaters.
Shahed-136 excels due to its proven effectiveness in large-scale operations and resilience in combat environments.
Strengths and Weaknesses
Samad-3's strengths lie in its 1500 km range and GPS autonomy, ideal for Houthi infrastructure strikes, but it's hampered by a small warhead and lack of terminal guidance. Shahed-136 boasts a larger warhead and low radar profile, excelling in swarm tactics as seen in Ukraine, yet it's slowed by its 185 km/h speed and susceptibility to jamming.
