Iran Deploys Small Submarines in Strait of Hormuz as Tensions Escalate

Analysis
With frigates Dena, Alvand, Sabalan, Sahand, Jamaran, and Deylaman among documented losses from February-March strikes, Tehran is anchoring maritime deterrence in an asset class whose coercive value operates through ambiguity rather than tactical performance, corroborated by Bloomberg and Iran International. The "trigger-ready" framing during Dena's memorial exercise may be primarily domestic resilience signaling rather than a genuine operational shift, but the distinction narrows in chokepoint conditions where shallow depths and dense traffic already degrade sonar performance. Acoustic, maintenance, and crew-experience deficits matter less against civilian tankers than against US Navy ASW. Iran will likely sustain a visible Ghadir presence through at least August as counter-leverage to Washington's convoy-escort proposal.
