Breaking news. South Korea has unveiled the Hycore hypersonic cruise vehicle launch. In 2024, it achieved Mach 6. Extremely advanced technologies were used, and anti-ship ability will be applied. land, air, and naval based variants are being prepared. The air-launched (KF-21) variant emphasizes gliding, while the sea-launched variant, mounted on destroyer's KVLS-II or KSS-III submarine's VLS, is expected to be similar to the land-based variant. There are at least five types of ramjet and scramjet engines. The Hycore uses an advanced dual-mode ramjet and a KTSSM booster.
S.Korea is developing both HGV and HCM, which is interesting considering the difficulty of HCM development. HGV are also easy for them, requiring minor modifications to the existing Hyunmoo-IIC and IV-1. Their missile propulsion, control, and materials engineering technologies are considered to be of exceptionally high quality. South Korea is known for not displaying its secret missiles at military parades. It would have been nice if they had been displayed at last year's parade.

According to recent seminars...
The KF-21's K-HCM is a different version of the K-HCM that does not require an interstage part.

It's surprising that Hyundai Heavy Industries has already delivered this many ships ordered by the Philippines. These include two classes of new frigates and a new OPV. I hope to see more new frigates in Peru and the Philippines. I'd like to see the HDF-4000 (FFG-III) and the HDF-6000. Well, Peru purchased an HDF-4000 similar AAW frigate model. HHI is busy with a lot of work to do in the US, showing great results these days. Hanwha Ocean, keep up the good work.
The LIG Nex1 should also consider making an export version of the SONATA, SONATA-II dedicate full-fledged electric warfare equipment for the Hyundai since they are actually one team.

An FA-50 armed with four KGGB glide bombs. It's good to hear about the FA-50 these days. Poland, Malaysia, and the Philippines are continuing to improve and obtain their FA-50 operational capabilities, and evidence of KGGB use in the recent conflict between Thailand and Cambodia has surfaced. While the FA-50 can certainly carry two large air-launched stealth cruise missiles (KALCM) and supersonic anti ship cruise missiles (Air to Ship Missile-II), no weapon is as suitable as the KGGB. I'd love to see photos of a Polish FA-50 armed with the KGGB soon.
I've previously described the KGGB's features, but to exaggerate, the KGGB's intuitive integration and controllability are so intuitive that even World War II torpedo bomber could use it.
I hope that countries operating the FA-50 or TA-50 will continue to purchase the KGGB in large numbers.
Of course, even without a Korean fighter, the KGGB kit and dedicated terminal pad are compatible with any platform.

Unlike JDAM-ER, the KGGB has Flaperon. This provides further enhanced maneuvering capabilities to KGGB.

Congratulations. The UAE is getting closer to purchasing the KF-21. One of the commanders of the UAE military himself boarded and flew the KF-21, which is the first time a high-ranking foreign military official has boarded it.
The UAE, like Saudi Arabia, is a country that has purchased Korea's cutting-edge weapons and is also a close strategic partner in the private sector. Notably, the UAE has purchased the M-SAM-II ballistic missile interceptor system and K239 MRLS and is close to purchasing the L-SAM high-altitude long-range interceptor system.
The Korean military has also conducted heavy equipment training and ballistic missile interception tests in the UAE and has also built a nuclear power plant in the UAE.

The KF-21 is a highly digitalized versatile fighter jet that can use various destructive Korean missiles.
Korea wants to use them as medium, large air-launched missile platforms.
Koreans have F-35A and F-15K, but it is extremely hard to use Korean weapons because of integration and airworthiness certificate matters, etc. The avionics, including the radar, are top-notch and have already passed extreme tests and are in production.
KF-21 will rapidly replace existing old jets.

Many people ask me about the situation in Indonesia. The Indonesian government has not paid the costs for a long year, and the Indonesian government and the Korean government ultimately agreed to reduce the technology that Indonesia will receive. Therefore, we can think of Indonesia leaving the position of 'joint development' a long time ago.

Two seats mean many things.. (marketing)
The KF-21 can be easily converted into a dedicated EW fighter.

Hyundai Heavy Industries said that it can build five Aegis destroyers for the US per year and is ready to expand. It also said that it can provide one ship per year to the US using its current spare dock, and that it has more room and cost-effectiveness than its competitors (Hanwha Ocean, Japan), and that it has over 250 veteran elite engineers required to integrate Aegis destroyers and combat systems.
It also said that a total of 12 domestic and foreign surface ships are currently under construction by Hyundai shipyards.
Take note that HHI is already rebuilding the navies of Peru and the Philippines.
Hanwha Ocean agreed to focus on submarines, while Hyundai Heavy Industries agreed to focus on surface ships.
Both companies are involved in the US Navy's massive MRO program.

So far, Hyundai Heavy Industries built three DDG-I Sejong the Great Aegis destroyers, and one DDG-II Jeongjo the Great Aegis destroyer.

Will South Korea eventually arm itself with nuclear weapons? All the evidence is pointing in one direction, and they seem to be fiddling with the last remaining door. Korea began developing nuclear weapons in the middle of the Cold War but had no choice but to voluntarily give them up at a critical moment.
And now, in 2025, they have the highest level of missile technology and the strong will to invest, but the key is how they will deploy weapons-level nuclear weapons and what strategic advantages they can gain.
Will their enemies’ stance change just because South Korea armed itself with nuclear weapons? Nevertheless, South Korea will develop a large military, long-range, high-precision mass strike capabilities, MD capabilities, and pursue various nuclear propulsion capabilities.
France model? Israel model? Whatever, newly established Korean Strategic Command is now bigger than ever. We shall see about that.
