On May 15, 2025, North Korean leader Kim Jong Un attended live-fire drills of an elite fighter wing based in Pyongyang, and inspected new air-to-air and ground attack weapons. While some of these weapons are non-operational samples, they demonstrated Kim Jong Un’s will to pursue air force modernization. Although this effort will not overcome the comprehensive and systematic disadvantages of the Korean People’s Army (KPA) Air Force, the technologies showcased during the May 15 drills could further contribute to North Korea’s land-based air defence capabilities. This potential cannot be overlooked, as in any high-intensity war, land-based air defence is expected to play a more critical role than Pyongyang’s fighter jets in delaying the destruction of North Korea’s nuclear weapons.
Advanced Air-To-Air Missile (AAM) Not Ready Yet
Although it may have appeared briefly in a KCTV report on the 2021 Self-defence Exhibition in Pyongyang, the May 15 air drill marked the official debut of North Korea’s advanced medium-range air-to-air missile (AAM). The missile has a layout similar to fourth-generation radar-guided AAMs such as the US AIM-120 and the Chinese PL-12 (Figure 1). Unlike earlier generations, fourth-generation radar-guided AAMs feature an active radar seeker that allows its launch aircraft to disengage as soon as the missile’s seeker locks on to the target, greatly increasing tactical flexibility and advantages for the launch aircraft.

However, in one of the KCNA photos from the May 15 drills, Kim Jong Un is seen standing in front of a MiG-29 fighter jet with one such advanced AAM mounted under its starboard wing. Notably, the missile was photoshopped into the image (Figure 2), suggesting that: 1) North Korea may be attempting to create the impression that the missile is nearing completion or already in active service, or 2) this AAM may still be in a relatively early development phase.

Sparrow Returns to the Peninsula?
During the May 15 drills, a MiG-29 apparently fired a previously unseen, and likely less advanced, mid-range AAM. This AAM, apparently also of radar guidance type, features large triangular control surfaces located at the midsection of the missile’s body, giving it a visual resemblance to the US AIM-7 Sparrow (Figure 3).

The Sparrow missile reached maturity in the 1980s, following two generations of development in radar guidance technology. The third-generation Sparrow, namely the AIM-7M/P variants and their foreign derivatives, remained the primary medium-range AAMs in Western air forces until the 1990s and 2000s, when they were gradually replaced by fourth-generation radar-guided missiles such as the AIM-120. Sparrows are all-the-way semi-active radar homing missiles. In this guidance mode, the launch aircraft’s radar continuously “illuminates” the target from launch to impact, allowing the missile to home in on the radar wave reflected from the target. Compared to active radar homing missiles, semi-active types offer limited tactical advantages.
Although the authenticity of the relevant KCNA photos (Figure 3) cannot yet be independently verified, the development of a less advanced radar-guided AAM appears logical for North Korea, given the relative simplicity of its engineering and manufacturing requirements (Figure 4). Despite tactical limitations, the third-generation Sparrow proved to be a potent air-to-air weapon, achieving a hit rate of over 50 percent during the 1991 Gulf War.[1] With South Korea’s AIM-7M missiles retired in June 2024 alongside their launch platform, the F-4 Phantom, the possible induction of this “Juche Sparrow” would mark an intriguing return of the AIM-7 lineage to the Peninsula.

The fact that the People’s Liberation Army also operates a reverse-engineered version of the Sparrow, the PL-11 AAM, makes China a possible source of proliferation in this case. However, the core technologies underpinning the third-generation AIM-7 are now over 40 years old, and it is plausible that the “Juche Sparrow” is, for the most part, an indigenous development. This is particularly likely given that North Korea’s MiG-29s were originally equipped with Soviet R-27 AAMs, whose seeker technologies are roughly on par with those of the third-generation AIM-7.[2]
Precision Glide Bombs From Exhibition Hall
In addition to the two types of domestically-developed radar-guided AAMs, Kim Jong Un also inspected two guided glide bombs: one apparently equipped with a satellite navigation kit, and the other with an optical terminal seeker. While the satellite-guided bomb is likely intended for use against fixed targets, the variant featuring a terminal optical seeker may not only offer greater accuracy, but could also be capable of engaging moving targets (such as ships), with the aid of mid-course correction commands from the launch aircraft.
However, serial numbers marked on the two bombs suggest they are most likely the same samples previously showcased to Kim Jong Un in May 2024 at the exhibition hall of the Academy of Defence Science (Figure 5).[3] This indicates that these airborne ground-attack munitions are not yet operational, although they may have been carried aloft by a North Korean Saetbyol-9 drone during the 15 May drills in what the KCNA described as an “application test.”

The placement of these non-operational samples alongside the AIM-120/PL-12–type AAM further reinforces the assessment that the advanced AAM on display is also not yet ready for deployment.
Technical Implications and Future Possibilities
Reportedly, of the 44 Sparrow missiles fired, 30 hit their targets and allegedly took down a total of 25 aircraft.
Except that the R-27 variants have an autonomous flight phase aided by mid-course correction commands from the launch aircraft, which allows the launch aircraft to delay the radar lock, improving survivability and engagement flexibility. In fact, the R-27 outperforms the AIM-7 in many metrics on paper. However, China’s decision to reverse engineer the third-generation AIM-7 instead of the R-27 may suggest that the latter is less satisfactory in reality. This assessment is in line with non-open source opinions on the performance of exported R-27 missiles.
The satellite guidance type was first revealed during a military parade on July 27, 2023.

According to KCNA photos, subsonic anti-ship cruise missiles were used to simulate incoming cruise missiles.

외형상으로만 추정한 것 같습니다. ARH, SARH 두 모델을 동시에 개발한다고 보는 것 같고, SARH는 지대공/함대공 미사일 베이스로도 써먹을 거라고 보는 것 같네요. 스패로랑 닮긴 했네요.
