Full Analysis Summary
IRGC Navy test summary
I cannot find any of the provided source articles that mention a ship named "Shahid Mahdavi."
The only article supplied — PressTV (West Asian) — describes a different IRGC naval event.
On Feb. 20, 2026 the IRGC Navy test-fired the Sayyad-3G naval surface-to-air missile from the Shahid Sayyad Shirazi during Smart Control exercises in the Strait of Hormuz.
The article states this was the first vertical-launch, long-range SAM deployed from an Iranian warship.
Because no supplied source mentions "Shahid Mahdavi," I cannot factually report that ship’s mission.
Instead, I summarize and analyze what the available source actually reports about the Shahid Sayyad Shirazi and Sayyad-3G.
Sayyad-3G technical overview
PressTV’s account focuses on the technical milestone and presents the Sayyad-3G as a maritime derivative of Iran’s Sayyad family.
It reports the missile is roughly 7 metres long with a launch weight near 2,000 kg, uses solid-fuel propulsion, can reach up to Mach 7, and has an engagement range of about 150 km.
The article frames these specifications as demonstrating Iranian efforts to indigenize advanced air-defence capabilities under sanctions.
PressTV says the missile is intended to extend naval air-defence reach and improve fleet survivability.
Coverage Differences
Narrative Framing
Because only PressTV is available, the technical framing (emphasizing indigenization and capability) cannot be contrasted with other source types (for example, Western mainstream assessments or independent technical analyses). PressTV’s framing foregrounds domestic technological progress under sanctions; no other source is present to confirm, challenge, or add context to those technical claims.
Missile guidance and features
PressTV reports the missile’s guidance architecture as a hybrid suite combining inertial navigation with data-link midcourse updates and active or semi-active radar homing in the terminal phase.
PressTV also reports the missile uses a vertical launch silo on Shahid Soleimani-class ships to provide 360° coverage and rapid salvo capability to counter saturation attacks.
The article notes a high-explosive warhead with a proximity fuse and claims of electronic protection/counter-countermeasure features, though it says those are not detailed.
Coverage Differences
Missed Information
PressTV reports claimed electronic protection and counter‑countermeasure features but does not detail them, and no other supplied source is available to corroborate or provide technical scrutiny. Consequently, the extent and effectiveness of those features cannot be independently verified from the provided material.
PressTV report on naval test
PressTV presents the test as significant for Iran's naval posture in the Strait of Hormuz, citing extended engagement range, 360° vertical-launch capability, and networked sensor integration.
The article says those features improve fleet survivability and the ability to counter saturation attacks in a strategically sensitive waterway.
It frames the test within Iran’s broader push to indigenize defence systems under sanctions.
Because no other sources are supplied, alternative interpretations — such as assessments of operational readiness, effectiveness against modern threats, or international reactions — are not available for comparison.
Coverage Differences
Narrative Framing
PressTV frames the event as a strategic advancement and part of indigenization under sanctions; without other source types provided (Western mainstream or independent analysts), there is no available contrasting assessment of operational readiness, potential limitations, or geopolitical reaction. This is an omission in the supplied source set rather than a contradiction between reports.
