1st generation. Radio command guidance with nuclear warhead.
First long range SAM in the world was US two stage MIM-14 Nike Hercules which entered service in 1958. Computer modulation showed that with nuclear warhead it could be used against ballistic missiles as well. In 1960 happened first successful interception test (of tactical ballistic missile).
On Nike Hercules base were developed two special anti ballistic missiles: 2 stage Nike Zeus A and much larger 3 stage Nike Zeus B with space interception capability. In 1962 Nike Zeus B carried first successful interception of ICBM. However Nike Zeus did not enter service.
On Nike Zeus B base was developed 3 stage LIM-49A Spartan, which entered service in 1975.
In USSR
In 1961 there was first interception of theatre ballistic missile with two stage V-1000 test missile.
In 1972 entered service A-35 anti ballistic system with A-350Zh two stage missile.
In 1996 entered service A-135 anti ballistic system with 51T6 two stage missile.
Nike Zeus B, Spartan, A-350Zh, 51T6 all had space interception capability (200-400 km altitude), but due to radio command guidance they all needed nuclear warhead for successful interception.
