Патриот — способная система ПВО, и она не устарела.
Вот подробное сравнение с S-400:
Ракеты:
Patriot:
- Патриот PAC 2 был выпущен в 1990 году. Его ракета имеет дальность действия около 160 км и имеет полуактивный радар. Ракета PAC 2 ориентирована на зенитную задачу.
- Существует также PAC 3, который более сфокусирован на противоракетной задаче, имеет дальность 20 \ 35 км (20 для базового PAC-3 и 35 для PAC 3 MSE), использует активную радиолокационную наводку и работает примерно с 2000 г. ,
- SkyCeptor, which is a slightly modified STUNER interceptor will be compatible with Patriot in the near future. Stunner (a part of David’s Sling) is a VERY capable interceptor. Its range is in exess of 160km, and it is revolutionary as it has 2 seekers- an IR and a radar, both mounted on the missile. It also has 2 stages, while the second stage has 3 pulses, making the missile capable of flying very far while maintaning a very high speed. It focuses on intercepting ballistic missiles and cruise missiles.
S-400
- 48H6N- this misssile was taken from the S-300. It is the russian equivalent of the PAC-2. It has a range of around 200 km and semi active radar homing.
- 9M96E and 9m96E2-these missiles are from around 2000 and were made for S-400. They have a range 40 and 140 km and active radar homing.
- 40N6- This missile reportedly has a range of 400km and will be used only against high value targets as AWACS. In 2015 it became operational, though that considering how new it is- there is no way that enough were made in order to field these in all S-400 batteries, but only a very small part of them. Also, there are no photos of this missile.
All of S-400 missiles are anti-aircraft focused.
See were I am going to? Patriot is not outdated at all.
Radar\s:
Patriot:
- AN\MPQ-53- This Radar is reletively old. It has a range of around 200km. It can do everything, from detecting, to tracking, to guiding missiles.
- AN\MPQ-65- This Radar is not operational yet, but there is a prototype. Its exact range is unknown. Just as AN\MPQ-53, it can do everything, from detecting to engaging.
S-400
- 92N6E Gravestone- This radar is used for engagment. It guides Semi active radar homing missiles (48H6N) and active radar homing missiles to the target.
- 91N6E Big Bird- This radar is used to detect enemy planes at long range. It can detect a stratigic bomber sized target at 600km, and an unstealthy plane (as F-16) at around 400km.
- 96L6E- This is an acquisition radar. It’s range is 5–300 km according to the developer.
- S-400 uses some more radars.
Off cource that the systems also have over componets as battle managment centers, but we don’t know enough information about them to compare them.
Verdict:
Both systems are very advanced. Currently, S-400 definetly the edge In terms of detection. In the anti-aircraft role S-400 has the edge, while patriot has the edge in the anti-missile role.
NATO countries do have an air defense system- MIM 104 Patriot. It is advanced and definatly not outdated, and as advanced as S-400.
