A zar to postavljanje nema kojim slučajem veze sa geografskom širinom s koje se očekuje lansiranje? Takođe se treba podsetiti putanja koje se zovu oktodrome i loksodrome.

Занимљив аналитички текст о кинеском С-300.

Издвајам:
S-300 Coverage of Taiwan Strait: This map from the 2005 issue of the U.S. Department of Defense�s annual report on PLA modernization shows that new S-300s can cover air routes used by international airliners landing on Taiwan, as well as illustrating the PLA�s ability to deny the air-defense buffer of the Taiwan Strait to the Taiwan Air Force.

Russia testing new missile for S-400 air defense system
CHKALOVSKY (Moscow Region), December 26 (RIA Novosti) - The Russian Air Force is testing a new missile for the S-400 Triumf air defense system, the Air Force commander said on Friday.
The S-400 (SA-21 Growler) is designed to intercept and destroy airborne targets at a distance of up to 400 kilometers (250 miles), twice the range of the U.S. MIM-104 Patriot, and 2.5 times that of the S-300PMU-2.
The system is expected to form the cornerstone of Russia's theater air and missile defenses up to 2020 or even 2025.
"The S-400 system is being successfully deployed with air defense units. At present, we are testing a new missile for this system," Col. Gen. Alexander Zelin said.
Russia successfully conducted last year live firing tests of the S-400 air defense complex at the Kapustin Yar firing range in south Russia's Astrakhan Region, and deployed a battalion of the first missile regiment equipped with the new system to protect the airspace surrounding Moscow.
The system is believed to be able to destroy stealth aircraft, cruise missiles, and ballistic missiles, with an effective range of up to 3,500 kilometers (2,200 miles) and a speed of up to 4.8 kilometers (3 miles) per second.
A regular S-400 battalion comprises at least eight launchers with 32 missiles and a mobile command post, according to various sources. The new state arms procurement program until 2015 stipulates the purchase of enough S-400 air defense systems to arm 18 battalions during this period.

Može li ni neko da objasni šta znači: "with an effective range of up to 3,500 kilometers" jel to domet radara ili cilja?

To je domet rakete koja se presreće i verovatno to određuje idealne uslove za presretanje u silaznoj putanji.

Hvala aramis s
Sada ta nova raketa bi onda morala biti 2 puta veča ako ima domet od 400km i da gađa cilj pri brzini od 4,8km/s ali koliko ja razumem veča (mislim na masu) je raketa manja je brzina koju postiže i obrunto. Kako su to postigli? Jeli u pitanju gorivo ili je nešto drugo?

Ja još uvek nisam video raketu koja je namenjena tom sistemu. Kada je vidim moći ću da pretpostavlam. Nadam se da me razumeš.

Pa ne mora. Efikasniji motor, naprednije gorivo, nova elektronika (manja tezina i naprednije pracenje), bolji vektorski potisak mogu da ucine cudo.

@sebab
Citat:kazu jos i delimicno uspesno
To ti je ono :"operacija uspela, a pacijent umro". Presretanje nije ništa ako cilj nije oboren ili skrenut sa putanje.
Mislim da je najveći problem kod tog sistema to što Ameri ne mogu da shvate da mora da bude velik i moćan kao i stari sistem Nike.
