Citat:
Robotar funkar bara om man vet att missilerna kommer i långa vägar i förväg och de kan dessutom flyga på väldigt låg höjd och mycket lättare kunna undvika radar, och när du pratar om artilleri så pratar du om besättning som ska försöka skjuta ner en missil som kommer i nästan 1000 km/h med kanoner. Inte så lätt, och allt detta är bara teoretiskt. Det är bara ryssarna som fått chansen att sätta dessa teorier om försvar mot kryssnings-/sjömålsrobotar till test rent praktiskt sett. 

USA har fått göra det några gånger. Har väl gått sådär:

Citat:
On 13 October 1989, USS El Paso was conducting a live-fire exercise off the East Coast of the United States using the Phalanx against a target drone. The drone was successfully engaged, but as the drone fell to the sea, the CIWS re-engaged it as a continued threat to El Paso. Rounds from the Phalanx struck the bridge of USS Iwo Jima, killing one officer and injuring a petty officer.
On 17 May 1987, during the Iran–Iraq War, an Iraqi [21] modified Falcon 50 business jet, [22] fired two Exocet missiles at the American frigate USS Stark.
Both missiles struck the port side of the ship near the bridge. The Phalanx CIWS remained in standby mode and the Mark 36 SRBOC countermeasures were not armed.[23] 37 United States Navy personnel were killed and 21 wounded.
On 25 February 1991, during the first Gulf War, the Phalanx-equipped frigate USS Jarrett was a few miles from the U.S. Navy battleship USS Missouri and the Royal Navy destroyer HMS Gloucester. An Iraqi missile battery fired two Silkworm missiles (often referred to as the Seersucker), at which time Missouri fired its SRBOC chaff countermeasures. The Phalanx system on Jarrett, operating in its automatic target-acquisition mode, fixed on Missouri's chaff, releasing a burst of rounds. From this burst, four rounds hit Missouri, which was 2–3 miles (3.2–4.8 km) from Jarrett at the time. There were no injuries on Missouri and the Iraqi missiles were destroyed by Sea Dart missiles fired by Gloucester.

Det är fina system på film/TV de här som skjuter ner inkommande missiler. Ser väldigt coolt ut! I praktiken verkar det inte fungera jämnt som vi nu såg även här med Moskva. De har 6 system för att bekämpa inkommande missiler.
