Most likely Israel used the Dolphin Class submarine in this strike, to get safe/ensured results especially after the Syrian air defense managed to down an Israeli F-16 during it last engagement with Syria.

3-the Dolphin class is capable of launching cruise missile form its torpedo tubes including the tomahawk missile and the Israeli made cruise missiles.

And judging by the numbers of missiles that Syria managed to shot down and the missile that hit its targets. They used 2 subs.

Israel used this tactic back in 2013, when they tried to hit a Syrian anti-ship missiles depot (Yakhont) somewhere near Latakia

Back then Israel used the Dolphin subs to attack.

Tonight the Syrian Air Defense Forces managed to down 8 missiles as the Syrian state TV stated.

The interception was done by the BUK-Pantsir system.

And I’m waiting for the wreckage images to identify what kind of missile Israel used (most likely Popeye Turbo SLCM)

Last but not least

Its reported that Russia has deployed its anti-sub hunter killer the IL-38N in Syria couple days ago.

Coincidence??
