The Defense Science and Technology Exhibition is in its seventh year, and not only did the Defense Science Research Institute directly participate, but various latest defense technology research projects commissioned by the Defense Acquisition Program Administration and the Defense Technology Promotion Research Institute were also exhibited.
Although there are no flashy weapon systems that stand out at the Defense Science and Technology Exhibition because major domestic defense companies do not participate, it was very faithful in terms of content because the top defense technology experts in Korea participated.
Among the various new technologies unveiled at the Defense Science and Technology Exhibition, we analyzed through Military Review Issue 2310 the smart multi-beam high-power transmitter that can be applied to the Korean-style electronic warfare system, and the nano conjugate structure stealth technology that can be applied to the KF-21 Boramae and stealth unmanned combat aircraft.
Smart Multi-Beam High-Power Transmitter
The Defense Science Research Institute exhibited <스마트 다중빔 고출력 송신장치> planned to be applied to the next-generation electronic warfare system project. Electronic warfare technology is classified as a secret technology, so it is rarely revealed, but this technology is a new technology currently under development, so not only was it exhibited at this exhibition, but we were also able to hear detailed explanations.
According to a related person, this technology is under development with the aim of applying it to the next-generation electronic warfare system, and it is a technology that can form a wideband multi-beam that can jam the 2~6GHz band at once.
More specifically, it is said to be a domesticated example of a new technology applied to the electronic warfare pod of the EA-18G Growler electronic warfare system, which the United States is developing for the ALQ-279 NGJ(Next Generation Jammer).
This is the U.S. Air Force’s EC-37B electronic warfare prototype. The U.S. Air Force announced that it will use the EC-37B to disrupt enemy command and control and suppress enemy air defense networks.
◆ Next-generation electronic warfare system in full swing!
On April 13, 2023, the Ministry of National Defense held the 152nd Defense Project Promotion Committee and deliberated and decided on a basic strategy for promoting a project to develop a next-generation electronic warfare system by 2032 with an investment of 1.85 trillion won.
Electronic warfare systems are largely divided into Escort Jammer models such as the EA-18G, which are modified from current fighters, and Stand-off Jammer models that are modified from medium-to-large transport aircraft or business jets.
The project decided this time is a stand-off type that modifies a transport aircraft or business jet, and can perform disruption against communication networks, radar, and data link systems from a long distance while operating from the rear of the front line.
So, what kind of model will be developed in detail? According to the related person, although the system has not been perfectly confirmed yet, it was revealed that they are pushing for the development project with the goal of a model equivalent to the EC-37B, which the U.S. Air Force is developing, and we were able to hear stories around it.
First of all, the development project of the Korean-style electronic warfare system was a series of trial and error. The Korean Air Force already submitted a development requirement for the Korean-style electronic warfare system development project in 2019, and it had passed the verification of the Joint Chiefs of Staff.
North Korea’s air defense network is mainly built based on the experience of the Vietnam War in the 1960s and 1970s, and consists of over 10,000 low- and medium-altitude anti-aircraft guns and over 10,000 SA-16 portable infrared guided missiles.
◆ Failed the Requirement Verification!
However, KIDA(Korea Defense Research Institute) failed to pass the requirement verification, more precisely the process of performing power requirement analysis, and the development project was scrapped in 2020.
In this process, when the requiring military requests the introduction or development of a weapon system, a power requirement verification committee under the Ministry of National Defense is established to verify the appropriateness and project priority of the weapon.
Here, power requirement analysis is a task of investigating and analyzing various aspects such as identifying issues of military requirements, examining feasibility and alternatives, policy issues, etc. In simple terms, it corresponds to a task of precisely analyzing the effect against cost.
So why did the Korean-style electronic warfare system fail to pass the power requirement analysis?
The related persons explained that the key reason was that the Korean Air Force failed to properly write the power requirement request. It only repeated the old logic that it was necessary to deal with the old North Korean air defense network, without properly specifying the real demander, the threat of neighboring countries.
