Air defense has been and will be a very important aspect of a nation's military capability.
In any modern battle scenario, air dominance is critical.
A credible air defense system makes it hard for the enemy to achieve air dominance and
because of this has a significant impact on battlefield strategies.
Modern air defense systems are capable of not only taking out aircrafts but also cruise
missiles, UAVs and some even have the capability to intercept ballistic missiles.
Major militaries have spent huge effort to design and field capable air defense systems.
In this video, Defense Updates compares AMERICA'S PATRIOT PAC 3 AGAINST RUSSIA'S S 400 and
find out which is better.
Lets get started.
The American Patriot Missile System is manufactured by Raytheon.
It entered service in1981.
Patriot systems have been sold to many countries like the Netherlands, Poland, Germany, Japan,
Israel, Saudi Arabia, Kuwait to name a few.
The Patriot system is expected to remain in the service until at least 2040.
Russia's S 400 is designed by Almaz Central Design Bureau as an upgrade of the S-300 family.
It entered into service in 2007.
The system has been sold to China and India has also committed to acquire it.
The radar is the eye of an air defense system and is used to detect and track targets.
The AN/MPQ-65 Radar in Patriot Pac 3 is a passive electronically scanned array radar.
It is equipped with IFF (Identification friend or foe) and electronic counter-countermeasure
to resist jamming.
The radar has a range of around 160 km.
S 400 uses multiple radars depending on threat perception.
The primary one is either the 91N6E Big Bird Acquisition and Battle Management Radar or
92N6E Grave Stone Multimode Engagement Radar These have range of around 600 km.
The main radar is complimented by target acquisition radars like 67N6 Gamma de and 9N6 Protivnik
ge radars in L band, Nebo SVN in the Very high Frequency band and Nebo m in Multiband.
The Nabob svn & Zebu m have claimed capability against stealth aircraft.
S 400 has radars with better detection range and the versatility makes it a winner in this segment.
Patriot Pac 3 introduced the new MIM-104F missile, which is also referred as the PAC-3 missile.
It has reduced size compared to previous Patriot missiles and is more maneuverable.
The missile uses hit to kill strategy though it has small high fragmentation warhead to
enhance the kill probability.
For aerial targets, like aircrafts & drones, Patriot MIM-104F missile has engagement range
of 160 km whereas for ballistic missile it has a range of about 30 km.
S 400 deploys multiple missiles to cover its full strike envelope.
1. Very-long-range 40N6 (400 km)
2. Long-range 48N6 (250 km)
3. Medium-range 9M96E2 (120 km)
4. Short-range 9M96E (40 km)
For aerial targets like aircrafts & drones, S 400 missile has maximum engagement range
of 400 km whereas for ballistic missile it has a range of about 60 km.
Clearly, the S 400 is equipped with missile having significantly more reach and gives
it a major advantage as it has much greater engagement range.
The maximum speed of targets for successful elimination is up to Mach 6.5 or 2,200 m/sec for Patriot
and Mach 14 or 4,800 m/sec for S 400.
So, S 400 can take down targets that the Patriot cannot handle.
This is very important as hypersonic missile are coming to fore.
The deployment time for Patriot is 30 min whereas its 5 min for S 400.
This means military commanders will find S 400 to more agile.
Launch angle of Patriot's missile is 38 degree whereas for S 400 its 90 degree.
The vertical launch enables missiles of S 400 to have seamless 360-degree target envelop.
As evident, S 400 has a better operational matrix when compared to Patriot Pac 3 and
will make it a more effective system in a battle scenario.
The Patriot is a system that is designed to provide medium range air and missile defense
over a small area.
It can be termed as a point defense system and suited to provide protection to vital
sites like air bases.
The S400 is a heavy-duty system that is designed to provide powerful air and missile defense
over a wide area.
Though primarily a defensive weapon, its incredible range gives it offensive capability when placed
near border region.
Russia's S 400 out performs America's Patriot Pac 3 by a large margin.
It is considered to be the most deadly air defense system and rightly so.
