.....................

After Shima class guided missile destroyer was in process of retirement, Honen naval command already work on new generation of guided missile destroyer. Originally American Arleigh Burke or Japanese Kongo classes were intend to be purchased as replacement for Shima class, however work on new ship already started. It took almost ten years from first designs to first ship been built and launched. However once launched Suruga was more powerful then any other destroyer on world including American Burke, Japanese Kongo&Atago, South Korean Sejong The Great and other classes. However Suruga had flaws, some which were dangerous and were immediately needed to be corrected.

While Honen itself was not in any danger from war like South korea and Japan. It did invest massively into Navy and Air force, and Suruga was most expensive modern destroyer ever produced.

Suruga use the same Aegis system and all other modern electronics that were found on Burke and Kongo classes, this saved some money and time despite design take almost ten years due constant design problems.

In term of weapons, Suruga carry more weaponry then both Burke or Kongo, but similar to Sejong the Great, although there were differences.

Main gun was locally produced 130mm naval rapid cannon, developed by Honen military firm Nomato. It has great range and was usually used against low priority targets when missiles and torpedoes were not needed.
There is two Mk II"Notachi" CIWS (close in weapon systems), these were licensed and improved variants of Vietnamese Palma CIWS. While Mk I was basically Palma, Mk II Notachi was locally built and was different. Difference lays in system. The Palma had two four barreled Gatling cannons, mounted on end of the arms with sensor been in middle, however, Notachi have one eight barreled Gatling cannon located in mid while sensor was located on top. Notachi have little better range then American Phalanx and sensor system is by far better then both Phalanx or Palma systems.

Suruga have 112 Mk41 VLS (vertical launching system), not the largest number of VLS as only other destroyer having more is South Korean Seyong the Great (Not counting the cruisers). But like Seyong and other guided missile destroyers it have large variety of missiles, like anti-air missiles, anti-ballistic missiles, anti-submarine warfare (ASW). Against ground targets, Tomahawk cruise missiles and Harpoon were the main weapons, together with 130mm bow cannon.
There is four torpedo launchers. These were installed into the low hull, two on each side of the ship. The system is pretty much advanced due taking very little internal space thanks to the fact that torpedoes that use (MU90 lightweight) need less space. Suruga carry total of eight MU90 torpedoes, four were always stored inside the launchers and other four in storage (which is always located on side of the torpedo tube and can quickly reload the second torpedo into the main torpedo tube by simply opening the side of torp tube and slide second torp in).

There is also four 35mm bushmaster cannons and from two to four M2 Browning machine guns for close combat.  However Suruga also carry revolutionary weapon system called the Upside VLS. These VLS are not launch their missiles in air as all modern VLS do, they launch them from the belly of the ship into the water itself. Two launcehrs were mounted on the sides of the ship close to the port and starboard side but pointing down instead up. These launchers launch the anti-submarine missile called ASVM-010 Seafire. Specially designed to fire under water. System is very complicated and it was one of most expensive weapon system on Suruga. First variant had problem as ship was need to be in deep sea to fire it, at least thirty to forty meters of depth before it could fire. Mk II variant which was introduced in 2018 reduce this to only ten meters of depth as missiles were pushed out of their launchers and then they move to their target at full speed. Suruga class ship is currently only ship in existence to have this type of weapon. US had similar system in development but due high price abandon the project.

Six Suruga class ships were constructed and they are the most important ships and largest destroyers in Honen navy not counting the helicopter carrier and Amphibious ships.
