Japan Kicks Off New Anti-Ship Cruise Missile Project

Known as the "new SSM," the missile is expected to help bolster the defenses of Japan's southern islands against possible Chinese aggression.

KHI's prototype missile certainly seems to match the general characteristics of the "new SSM," if not beyond the company's name choice. Quoting KHI officials, Naval News reports that KHI's “island defense anti-ship missile” is designed for high maneuverability over long ranges. It will be able to be employed from warships, aircraft, and land-based launchers, and could be modified to enable launch from submarines. In terms of its engine, KHI's missile will be fitted with the KJ300, a new turbofan engine currently under development by the company.

I wonder how this new cruise-missile will compare to the Storm Shadow and Taurus?

I don't think they would even be in the same category. The Taurus and Storm Shadow are both air launch capable, but the KHI missile likely will be only land and sea based with maybe the P-1 having the capacity to carry it. Also comparing range.
Taurus is >500km
Storm Shadow is ~550km
This new missile is shooting for 2000km range.
The better comparison for this missile is to Tomahawk Vs with the 12SSM-ER a better comparison to those other missiles.

It has only tail fins with no apparent control-surfaces and no wings, how is this supposed to function?

No doubt a very public and pointed message to the Norks.

Japan Plans New Missile Range In Southeastern Island - Naval News

Japan Ministry of Defense is planning to establish a new missile range in the island of Minamitorishima for the Type 12 Surface-to-Ship Missile
www.navalnews.com

To make matters worse, Japan is introducing all kinds of domestic and foreign Long Range Stand-Off Missiles as part of a recent force buildup, most notably the improved Type 12 SSM with 745 miles (1,200km) of range which is unprecedented for the JSDF. This forced the Japanese Ministry of Defense to rethink how they could create more live firing training (and testing) in the long term.

I think the solution is to just do regular rotations through Australia like what is planned for the F-35. Japan is already starting up it's program of regular deployment rotations of F-35s to Australia, so it wouldn't be too hard to expand that agreement out. Japan has already done multiple live firings of shore based AShMs out of Australia and I'm sure they wouldn't mind having a regular rotation of Japanese AShM batteries that could cover the entire Banda Arc from Darwin. I can see the issue with having to ship the batteries all the way out there, but if this Minamitorishima range doesn't work out then it's a good fallback point instead of having to ship them all the way out to the US like with what was done before.

For testing, it's not any shorter to Aus than it is to the US.

But for an active deployment it's a good idea.

Translation would be fine. Any Japanese here? What are the different front sections?

Different mission payloads

Attack payloads:

1. Dual seeker: Both ARH and IR for anti-ship
2. IR seeker for anti-ground
5. Armor piercing warhead. It seemingly uses the IR seeker, so likely for bunker busting or hitting reinforced buildings. I wouldn't be surprised if there is an option for the dual seeker for carrier strikes too.

Preemptive? launch. Basically fired before a volley of attack payloads:

3. Jammer and Decoy, functions as both SEAD in the denial sense (no info on if it has a home on emissions mode, but the ASM-3 does, so likely) and can create multiple false radar signatures to fool incoming missiles.
4. EO/IIR sensor for attritable photo reconnaissance and feed advanced priority target information to the missiles in the main attack force.

What is so special about the turbojet/turbofan shown? Sorry, can't read Japanese language ....

To explain it well, we need to look at the KJ300 which was the previous version.
1731474938283.png
It has
365kgf SLS (sea level static) thrust
0.66kg/kgf/hr SFC (specific fuel consumption)

The F107-WR-400 on the Tomahawk has
288kgf SLS
0.683kg/kgf/hr
So the KJ300 has higher thrust and uses less fuel at that higher thrust thanks to a twin-shaft design. The KJ300 also has a 7kW power generation capacity.

For the XKJ301-1 the goal is to reduce the size and weight while keeping the same output and decreasing the cost.

They also want to adapt a variant for loyal wingman drones with 10kn (~1020kgf) thrust and 100kW power generation in order to handle the electronics and processing needed for combat drones.

Thanks Kota!

I didn't realise the Tomahawk turbofan has such a lower thrust when compared to KJ300, and yet Tomahawk seems to have enough thrust to carry out its mission .....

There is one more iteration being the WR-402 which does have around 315kgf SLS, but I couldn't findany SFC on it, but it likely would increase over the 400 anyways. The KJ300 is still a really impressive turbofan to come out of KHI and I hope we get specific numbers on the KJ301 to know how much the size has been reduced.

Actualy one would have to compared F415 with KJ300 as its the standard engine since TLAM / Block IV. Slightly more thrust than F-107-WR-400 (around 0.3kN) but mutch less efficient.
 

Japan unveils first images of new Type 12 anti-ship missile tests - Naval News

Japan's ATLA released images for the first time showing the launch tests of the improved version of the Type 12 anti-ship missile currently under development.
www.navalnews.com
The Type 12 SSM originally had a range of about 200 km. The new upgraded version aims to extend the range to at least 900 km, and eventually to 1,200 km. The shape of the missile has also been modified to reduce the radar cross section (RCS) and make it stealthy. The “Type 12 SSM (Upgraded)” will also implement Up to Date Command (UDTC), which allows the missile to receive information about the target via satellite communications while in flight and more accurately attack moving targets.
