In Photos: Booster Engines Of Syrian S-75 Surface-To-Air Missiles Employed In Encounter With Israel

“Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It scored the first destruction of an enemy aircraft by a surface-to-air missile, with the shooting down of a Taiwanese Martin RB-57D Canberra over China on 7 October 1959 that was hit by a salvo of three V-750 (1D) missiles at an altitude of 20 km (65,600 ft). This success was credited to Chinese fighter aircraft at the time in order to keep the S-75 program secret.[3]

This system first gained international fame when an S-75 battery, using the newer, longer-range and higher-altitude V-750VN (13D) missile was deployed in the 1960 U-2 incident, when it shot down the U-2 of Francis Gary Powers overflying the Soviet Union on May 1, 1960.[4] The system was also deployed in Cuba during the Cuban Missile Crisis, when it shot down another U-2 (piloted by Rudolf Anderson) overflying Cuba on October 27, 1962, almost precipitating a nuclear war.[5] North Vietnamese forces used the S-75 extensively during the Vietnam War to defend Hanoi and Haiphong. It has also been locally produced in the People’s Republic of China using the names HQ-1 and HQ-2.”

Assad is on survival with S-75 from 1957, while Russia, Israel and US is using Syria as a weapon exhibition and test laboratory.

it’s not designed to engage SSM missiles

Houthis would have already dug it up, refilled it and used it against the Wahhabi invaders. And they would have done it without shoes (but with the requisite cheekfull of khat and plenty of jabbering).
