(See) Japans neue Großzerstörer
#1
Der Titel mag etwas irritieren, denn genau genommen handelt es sich bei diesen Schiffen, sollten sie denn so gebaut werden wir geplant, nicht mehr um Zerstörer, sondern eindeutig um Schiffe in der Kreuzerklasse. Wir reden hier von einem zwar als "DDG" anzusehenden Schiff, welches allerdings eher einen Kreuzer zur Abwehr ballistischer Raketen (BMD) darstellt.

Diese Schiffe sollen ca. 210 Meter lang sein und um die 20.000 ts verdrängen, womit sie neben den alten russischen Atom-Kreuzern der Kirow-Klasse die größten Überwasserkampfschiffe wären, die keine Flugzeug- oder Helikopterträger oder Landungsschiffe (oder Atom-U-Boote) sind. Auf jeden Fall ein interessantes Vorhaben...
Zitat:New Details On Japan’s Future BMD Vessels Revealed

On August 31, 2022, Japan’s Ministry of Defense (MOD) released its budget request for FY2023, which included a line item on Aegis system-equipped vessels (ASEVs). However, no specific budget amount was given for this, as its details have not yet been finalized. The Japanese government intends to revise its national security-related policies, including the National Security Strategy, by the end of this year, which is why budget amounts for many items were not indicated as of the end of August. [...]

According to local newspaper reports, initial details of the ASEV point towards a massive ship: 210 meters long and 40 meters wide, with a standard displacement of 20,000 tons and a crew of about 110 people. Crew comfort onboard will be a priority as all crew members will be provided with private cabins. In terms of length and displacement, it is equivalent to the Izumo class DDH (248 meters long, standard displacement 19,500 tons), the largest vessel in the JMSDF, but it is more like a civilian vessel than a warship in that all crew members are given private cabins and the crew complement is quite low for a vessel of this size. [...]

However, according to press reports, the ASEV will be equipped with SM-6 missiles to deal with cruise missiles and anti-ship missiles, as well as an improved version of the Type 12 ship-to-ship missile that can attack surface targets as well as naval vessels and has a range of approximately 1,000 km. Therefore, the ASEV could become an asset that could respond not only to North Korean ballistic missiles, but also to attacks by Chinese ballistic missiles, HGVs, and cruise missiles. The question then would be how would the ASEV respond to the threat of Chinese submarines and anti-ship missiles. Above all, in this case, the ASEVs should probably be planned as a completely new type of warship, since it cannot be positioned as a mere alternative to the Aegis Ashore.

Zitat:Japanese MoD Releases Further Details Of ASEV BMD Destroyers

On Dec. 23, Japan's Ministry of Defense announced its fiscal year 2023 budget request, in which we may learn more about Japan's future ballistic missile defense (BMD) destroyers, commonly known as ASEVs (Aegis system-equipped vessels). [...]

The document released by the MoD describes the need for two vessels to let the other AEGIS vessels focus on different missions, and stressed once again the utility to have ships with superior capacities than the existing Aegis destroyers – able to cope with current ballistic threats, but also to neutralize hypersonic glide vehicle (HGV). To do so, the vessels shall be equipped with SM-6 missiles from Raytheon, a ship-launched derivative of the Type 12 SSM, and other undisclosed capabilities. In addition, the extract about ASEVs mentions the fact that the ships should be able to welcome future under-development missiles like the U.S. hypersonic missile interceptor. The picture released with the document – the first official one – confirms the ships should have not less than 64 VLS cells – 6×8 VLS on the front deck and 4×8 above the helicopter hangar – to host all those missiles.

Regarding the technical specifications of the ships, nothing is mentioned. But like Naval News reported a few months ago, according to local newspaper reports, initial details of the ASEV point towards a massive ship: 210 meters long and 40 meters wide, with a standard displacement of 20,000 tons and a crew of about 110 people.

Nun ja, wenn man nach NATO-Standards gehen will, die ja die Typ-055-DDGs der Chinesen mit ihren kolportierten 13.000 ts und ihren 110+ VLS-Zellen als Kreuzer definieren, so könnte man durchaus berechtigt diese neuen japanischen "Großzerstörer" besser als Lenkwaffenkreuzer einordnen. In jedem Fall aber sind es bemerkenswerte Konzepte.

Zitat:Japan Requests Largest Defense Budget Ever

The Japanese Ministry of Defense (MoD) on August 31 requested $52.9 billion (7.7 trillion yen) for fiscal year 2024, its largest ever defense budget request. Plans include the construction of two ASEVs and two new FFMs. [...]

The defense ministry explained at its budget request for the next fiscal year 2024 that the new ships will be 190 meters long, 25 meters wide, and have a standard displacement of 12,000 tons. In comparison, the two Maya-class Aegis-equipped destroyers are 170 meters long, 21 meters wide, and have a standard displacement of 8,200 tons.

The ministry pointed out that the size of the ASEV will be 1.7 times as large as that of the US Navy’s latest Flight III Arleigh Burke-class guided-missile destroyer. The ASEV will have a crew complement of about 240, which is much fewer than the Maya-class destroyer’s 300 crewmembers.

The Japanese Maritime Self-Defense Force (JMSDF) is expected to take delivery of the first ASEV during fiscal year 2027, with the second one in the following fiscal year. The ministry expects the construction cost per ASEV will be about $2.7 billion eventually.
