First of all, Japan may have some technological edges over China in terms of submarines, but naval technology, not so much the case. For example, Japan has AEGIS destroyers, but most of the sub-systems were actually American technology, not indigenous Japanese technology. Please correct me if I'm wrong, but I'm pretty sure Japan's best destroyers, the Atago Class, uses American radar, American missiles, American VLS, American guns, and even the design is almost identical to the Burkes.
To my knowledge, Japan didn't develop her own large AESA radar arrays that's comparable to the SPY-1 or the Type 346/346A, Japan didn't develop her own universal VLS, let alone several different VLS like China did.
Whoa, slow down their chief. You are getting a little too defensive.
No one is belitteling the PLAN capabilites.
While it is true that the Kongo and Atago vessels are AEGIS ships that incoprorate and employ predominantly US technologis...that is not all that the Japanese have.
It would be a huge mistake to think or say that the Japanese do not also have their own indegenous systems and a very srong indegonous C4SRI capabilities, including all that goes with it. I believe that their technology in this area is infact several years ahead of the Chinese.
A good example is their newest class destroyers:
These destroyers do do not use AEGIS. They use the Japanese own indegenous ATECS battle management system and sensors that rival the AEGIS capabilitiy. They commisioned the latest two of these DDGs March 13 and March 14, 2014.
The ATECS system is routinely called the Japnese AEGIS System, and is used on the Akizuki DDGs, the Hyuga DDHs, and their new Izumo Class DDhs. The Hyuga and Izumo classes are impressive aircraft carreir type vessels.
The ATECS system is comprosed of the following:
OYQ-11: This is a strong, Japanese indigenous CDS adopting fully distributed computing architecture with AN/UYQ-70 workstations and Link 16 capability for communicating with and controlling general-purpose destroyers of the JMSDF. In addition to the CDS, this class is equipped with SATCOM terminals with Superbirds for the MOF system. The MOF, Maritime Operation Force System is the operational C4I system used by the JMSDF, based on the ILOG architecture and interoperable with other JSDF forces. And there are also USC-42 DAMA terminals for also communicating with GCCS-M, which is the American counterpart of the Japanese MOF system.
FCS-3A: This is the Japanese anti-air warfare component of the battle management system. It consists of two main parts. The first is the Japanese dual-band, multimode radar system,. The second is the fire-control system. The FCS-3A system is the derivative of the FCS-3 system first introduced on the Hyuga class,. The FCS-3A system added a local area defense (LAD) capability to allow for integration of the ESSM.
OQQ-22: ASW and EW capabilities for ATEC include the OQQ-22 integrated sonar suite sub-system. This includes the hull-sonar and the OQR-3 towed array. This is the Japanese equivalent system to the US Navy AN/SQQ-89) and the NOLQ-3D digitalized EW suite sub-system. These sub-systems are integrated with a NOYQ-1B Wide area network
Japan worked closely with Thales to develop the X band Mid Course Guidance with Sampled Data Homing system for ATECS. This capability is called ICWI. The Japanese system allows their vessels equipped with ATECS to intercept numerous simultaneous incoming missiles. Japanese scientiest, working with Thales, indicate their belief that each single JMSDF vessel equipped with ATECS has the targeting, tracking, and simultaneous launch capability of two to three Arleigh Burke class destroyers.
Japanese ICWI is based on semi active homing. With semi active homing, the target is tracked and then illuminated by the ship. At the same time, the missile tracks the target with a purely passive radar and also homes in on that reflected energy. The idea is that the missile has less trouble sorting out the target from its surroundings, compared to a purely active homing missile. An added, critical advantage of ICWI is that very large amounts of illumination power can also be brought to bear on any target to burn through jamming and and EW efforts by the incoming missile.
These are the types of things the Japanese have already developed indegenously themselves for their surfact combatants...and deployed.
Yes, the Japanese and US Navy work closely together. And yes, the JMSDF employs a lot of US technology. But as I said, it is not all they they have. They are very advanced in their naval technology.
Stating this, is in no way an attack on, or belitteling the PLANs own systems. It is just indicating that the JMSDF has advanced indegenously in this area.
