Courtesy the Forbes Internet web site the article by our good friend H I Sutton:
"Video Shows Massive Iranian Navy Submarine Being Moved By Road"
"Iran’s three Kilo Class submarines are the most potent warships in their navy. A video has surfaced on social media showing one of them being transported by road. With the serviceability of the fleet in question, it may be revealing. The move does not appear to be routine. The implication is that at least one of the boats is not currently seaworthy."
That apparatus the submarine rests on a one-of-a-kind manufactured strictly for this one movement? From the wiki the displacement of the Kilo not submerged 2,300–2,350 tons. Actual road movement to be tenuous and slow I assume. A special roadway even needing to be constructed?
H.I. SUTTON CORRECT! HARDLY THIS A ROUTINE PROCEDURE.
