40 mm airburst rounds from K-21 IFV's K40 Autocannon footage has been released. Apparently, it seems better than the K30's 30mm AA gun. Perhaps it is better to increase the storage ratio of 40mm HE and MMFA rounds compared to 40mm APFSDS rounds for the K-21 IFV. One of the features of the K-21 IFV is that it is capable of anti-air engagement thanks to its advanced FCS and 40mm MMFA (K236) ammunition. However, the K30 has the distinct advantage of possessing its own volume search radar capability and the ability to use missiles. Modifying the K-21 IFV for air defense, like Sweden's CV90 (Lvkv 9040), is a decent idea, but since the K30 Biho SPAAG and K31 Pegasus self-propelled SAM already exist, it would be difficult to expect such a derivative product. God, I love this system.

🇳🇴🇰🇷 Breaking news. The Norwegian government and a majority of parliament decided that they would purchase South Korea's K239 long-range missile system and 500km range ballistic missiles instead of the European and Israeli PULS and MARS-3. A Norwegian Conservative politician says this is one of the most powerful weapons in Norwegian history and a crucial investment in modern defense. According to the recommendations of the Norwegian Ministry of Defence, the approval of the Norwegian Cabinet, and my sources at a Norwegian defense consulting firm, the contract is worth $1.88 billion and will involve the purchase of 15 to 23 launchers. A contract is expected to be signed soon. This would make Estonia the first official buyer of the CTM-MR medium-range tactical missile, and Norway is the first official buyer of the CTM-X ballistic missile. Norway, Poland, and Estonia also operate Hanwha Aerospace's K9 self-propelled howitzer, and South Korea has been discussing this with Norway for several years. So, it was expected. ●The existence of the US HIMARS option is currently unconfirmed. ●The Norwegian K9 is named VIDAR, the son of Odin. What will the K239 be named? ●Two major defense investment projects have been confirmed for Norway. One involves purchasing two additional submarines from the previously approved submarine program, bringing the total to six, with the budget reportedly increasing from NOK 52 billion to NOK 98 billion. The other is the LLPI program, a long-range precision-guided munitions program for the army (NOK 19 billion). ●South Korea, Poland, Saudi Arabia, the UAE, and Estonia have purchased the K239, and it is being offered to Norway, Egypt, Latvia, and Lithuania. ●The K239 MRLS can operate a wide variety of general purposes, special purposes, medium range, and long-range missiles. K239 version 3.0 is now underway.

Hyundai Rotem has released cool footage of the Polish K2PL. It looks like Leopard 2A8. It will also become the standard model for export to Romania, Saudi, the UAE, Egypt, Iraq, and Peru. K2PL boasts four key features. First, Hyundai Rotem's new APS is impressive. While similar to the Israeli "Trophy," it uses "Trophy" interceptor. (Think about the iPhone, which uses components from Korea and Japan.) The main computer, high-resolution AESA radar, optical sensor, launcher, loading device, and integration are all from Hyundai Rotem and unknown Korean sensor company. Second, it features upgraded special armor. It appears the existing state-of-the-art internal armor will be replaced with the latest technology from Samyang, minimizing volume and weight to improve overall performance. The third and fourth features are the anti-drone jammer and RCWS, which have been covered numerous times, so I'll skip them. Note that this footage is based on the 2024 KADEX, and the final design is likely to differ slightly. There's another AESA radar for the APS described previously, supposed to be located on top of the turret. It's unclear whether the K2PL will be applied to later batches. ●The name of the Hyundai APS has not been decided. ●Hyundai Rotem and Hanwha Group's APS are successors to the APS-11K, developed 17 years ago. Hanwha Group's APS looks similar to the APS-11K. ●The Hanwha Group's new APS is unlikely to be applied to the K2. ●The K2, an MBT released after the 2000s, is fundamentally highly digitalized and uses new materials to reduce weight. This reiterates the point, which has been circulating on social media, that more weight doesn't necessarily mean more survivability. ●As weight increases, overall performance deteriorates, and maintenance costs skyrocket. There's a reason why the global MBT development trend is toward lightweighting. ●Protecting vital areas is crucial. ●Of course, you can use cages and thicken the armor if you wish. ●The K2's unique active tank suspension contributes to the platform's expandability and contributes to its top-notch driving performance and combat capabilities. Self-hull-down technology improves detectability and protection in desert, flat, and mountainous terrain. In any case, performance isn't a crucial factor in combat platform transactions, as it's negotiable for large companies with robust solutions. In weapon acquisition, packaged price is the most important factor, followed by localization, time, offsets, and so on. This trend is particularly evident in naval combat platforms. While platforms can be expanded at any time, combat systems(most important), ammunition, and missiles, which account for at least 20-50% of the cost, are non-negotiable. I hope that the true meaning of the next-generation K3 tank will also do well in exports.

🇰🇷🇷🇴 Korean Hyundai Rotem unveiled its first live demonstration of K2 tanks in Romania. God, I love that design, especially that futuristic advanced turret structure. The K2 is excellence in any terrain and environment. In Romania, K2's superior firepower, mobility, sensor, viability makes the K2 like an tank sniper. They actually showed K2's self hull-down! They said "Hyundai Rotem, Long-term Strategic Partner for Romania's Defense!". I posted on here about contract details of K2 for Romania so please check out below. To short, we will do what all we can.

Congratulations, Egypt. 🇪🇬🇰🇷 Egypt will be the first of the 10 countries that operate K9 artillery to have anti-ship capability as a coastal defense purpose. Hanwha Aerospace said it exported 51 K11 fire direction control vehicles and 216 K9A1 SPHs to Egypt, and the K11 was modified for an anti-ship mission. It appears that the K9 has unimaginable potential as I expected. It would be great if Egypt had K239 long-range rocket artillery and K9A2 or K9A3 long-range SPH. (K9 proved its anti-ship capabilities in Egypt before the contract) South Korea, Turkey, Poland, Norway, Estonia, Finland, India, Australia, Egypt, and Romania are the current K9 family users.

Rare footage of American Harpoon and Korean C-Star anti-ship cruise missiles. Definitely overkill. Made her as scrapped metal. The C-Star proved its power in both the Colombian and Philippine navies, sinking ships with just one shot. C-Star will soon have an upgrade. I wonder when they will show their coastal defense supersonic cruise missile just like this video.

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.

🇵🇱🇰🇷 Poland has released a live-fire video of the Homar-K rocket artillery's CGR-080 missile for the first time. Cooperation between Poland and Korea knows no bounds. Poland also has the CTM-290 tactical ballistic missile. We expect Poland to operate the devastating CTM-MR (formerly CTM-160) and KTSSM-II missiles. It is also said that Polish rocket artillery operators are now very mature level. K239 MRLS is the world's second most-produced modern rocket artillery after the American systems. It is currently in service in large numbers by South Korea, the UAE, Poland, and Saudi Arabia. As you can see, Hanwha provides various choices for customers by using users local systems. Homar-K consists of Polish Jelcz truck and Topaz fire control system. Will Norway, Philippine, and Malaysia buy it?

South Korea is known for its love with firepower and missiles, and they've equipped their 250ton high-speed boats with 130mm missile launcher platforms, 76mm guns, advanced sensors, and electronic warfare systems. Looking at it this way, PKMR looks odd but also cute. Anti-ship cruise missiles are too expensive and bulky, 90mm LOGIR missiles are limited, and the naval version of the 239mm CGR-080 or CTM series rocket artillery is expensive and overpowered for the PKMR's mission. Therefore, the development of the 130mm Biryong missile was a logical choice. As you might have guessed, the PKMR was designed for immediate and simultaneous interception of a rush of North Korean vessels.

Footage of Polish soldiers suppression fire with a K6 heavy machine gun. 🇰🇷 : No burst, just shoot full-auto. 🇵🇱 : Ok 😉 The DCL-120 scope from DI Optical mounted on the K6 is impressive. DI Optical is famous for various high-end scopes. It is said that personnel from Romania, Poland, Australia, Vietnam, Egypt, and Turkey are being dispatched to the Korean Army to receive in-depth training in the operation of the K2 tank and K9 self-propelled howitzer.

🇪🇪🇳🇴🇵🇱🇦🇪🇸🇦🇰🇷 Estonia has placed an additional order for three units of the K239 rocket artillery. Some may say that this is insufficient, but just because Poland and South Korea operate a large number of K239s, it does not mean Estonia ordered less. The K239 can be considered as a modernized, wheeled version of the M270. Since the firepower of the M270 is double that of the HIMARS, a simple calculation suggests that Estonia will possess the long-range missile projection capability equivalent to about 18 HIMARS. In addition to the three types of basic medium-range and long-range missiles contracted with Estonia, various CTM and KTSSM series missiles are under development, so it will be interesting to see how that turns out. The K239 Gungnir, a special variant for Norway, incorporates HPRS technology, but Estonia does not seem to be very interested.

Breaking news. Norway has selected Hanwha's K239 system and 500km range ballistic missiles over SAAB/Boeing, KNDS, and Rheinmetall proposals as part of the acquisition of the long-range weapon system. Hanwha is the only company that met all requirements, including performance, delivery, and cost, according to the official announcement. The contract is worth roughly $2 billion and includes three kinds of missiles, 16 launchers, and comprehensive logistics and training. ●SAAB/Boeing did not submit their bids by the March 2025 deadline, while Norway also considered HIMARS through Lockheed Martin and FMS. ●KNDS was reportedly eliminated from the competition in June 2025. ●Hanwha plans to deliver launchers by 2029 and missiles by 2031. ●Hanwha recently signed a contract with Estonia and is offering the K239 to countries in the Middle East, Northern Europe, the Baltics, Eastern Europe, and Asian countries that don't have K239. (Latvia, Lithuania, Finland, Sweden, Egypt, the Philippines, Malaysia, etc.) ●Estonia and Norway are expected to engage in training exchanges with Poland on system operation. A rocket factory for Hanwha-WB Advanced Systems is scheduled to be built in Poland, and the ammunition produced there will be sold to various K239 family users. ●Currently, the K239 is in mass operation in South Korea, the UAE, Saudi Arabia, and Poland, and, along with HIMARS, is the world's most widely produced modern rocket artillery system. ●Hanwha Group has total solutions for tactical, operational, and strategic missile sectors, and they're actively promoting its high-altitude interception solutions. (L-SAM, L-SAM-II) ●The K239 MRLS can operate a wide variety of general purposes, special purposes, medium range, and long-range missiles.

Hyundai Rotem has released a video introducing the LRAAM missile. It is currently being jointly developed with LIG Nex1. The integrated ducted ramjet propulsion is shown briefly. ●The difference from the initially revealed LRAAM is the addition of strakes. ●Since South Korea's numerous air-launched strike missile programs are considered first and the existence of the MBDA Meteor, the development period is generous and is scheduled to end in 2032. ●The consortium is competing with Hanwha Aerospace. ●The SRAAM short-range air-to-air missile is being developed by LIG Nex1. ●The solid fuel gas generator generates fuel-rich gas through primary combustion. Air entering through the air intake is mixed with the fuel-rich gas and then combusted a second time in the combustor to generate thrust. ●Ducted ramjet or ducted rocket propulsion systems simplify the fuel supply system and are lighter than liquid-fuel ramjet propulsion systems. Liquid-fueled ramjets offer better fuel efficiency and fuel supply control. However, they require additional fuel handling and are more expensive and heavier. ●As part of the recent success of its ground-launched hypersonic cruise vehicle, Hyundai Rotem also released CG of an air-launched hypersonic anti-ship cruise missile. The disclosed information mentions the use of hypersonic cruise missiles on land, sea, and air, and Hyundai Rotem is considered to be leading the way in cutting-edge engine and materials technology. ADD and Hanwha Aerospace are also participating in this sensitive program.

Incoming another news. Estonia is said to be purchasing the K239 long-range missile artillery system soon, as it should be. Next up is Norway. South Korea, the UAE, Poland, and Saudi Arabia currently operate this system on a large scale. It can also operate a range of missiles, from general-purpose, various special-purpose missiles, and 500km range of CTM-X ballistic missiles, which Estonia might like. The K239 is currently available version 3.0, and a system similar to HIMARS, called HPRS, has also been unveiled. Current political, logistical, and policy issues between Israel, the US, and Germany pose significant risks from procurement to actual deployment. Hanwha Aerospace's K239 and HPRS are available without any political, policy, religious, agenda, logistical, and production conflicts. A contract with Estonia is expected to be signed within a few weeks, and Estonia is said to have requested a munition & MRO factory. Estonian military officials also said they are in talks with Poland to collaborate on training and education for the K239 system. ●The video shows the Homar-K launching a CTM-290 ballistic missile and reloading the pod. ●Estonia and Norway are also users of the K9 self-propelled howitzer. ●They are also in talks with Egypt and Southeast Asian countries regarding export.

🇪🇪🇰🇷 Estonia's purchase of South Korea's K239 rocket artillery system seems close. I thought Norway was expected to be the first to buy. The K239 MRLS is the third most produced modern rocket artillery system after the US HIMARS&M270. South Korea, Poland, Saudi Arabia, and the UAE operate large numbers of K239, and it's highly likely that Korean&Polish-produced (WB Group&Hanwha) ammunition will be supplied to Estonia. The K239 Chunmoo MRLS can operate missiles with a range of 500km and can also fire a variety of special-purpose missiles like L-PGW, KTSSM-II variants, and CTM-ASBM. While not everything is certain, the fact that the defense ministers of both countries met in person and signed a mou is a very positive sign. Estonia is also a user of the K9 self-propelled howitzer.
