新型弾道ミサイル：
「玄武4」（仮称）の試射は、失敗に終わりました。
GP（監視哨所）銃撃事件：
今月3日｢北朝鮮軍によるGP（監視哨所）銃撃時、遠隔射撃システムが正確に作動しなかったこと｣も、明らかになった。
韓国軍は北朝鮮対応態勢の面で、総体的な問題点が表面化した。
韓国軍内外の懸念：
韓国軍内外では「北朝鮮が実際に挑発してきた場合、韓国軍はきちんと対応できないということもあり得る」という懸念が浮上している。
「玄武4」：韓国軍関係者
5月11日に発表、
- 「今年3月に忠清南道泰安郡沖で玄武4の初の試射が行われたが、失敗」
- 「原因は推進体の異常」
- ｢今回、試射した2発の玄武4のうち1発が、不発｣
と伝えられている。
韓米ミサイル開発指針：制限解除
韓国軍は2017年11月、韓米ミサイル指針により「射程800キロ、弾頭重量500キロ以下」という制限が解かれた。
その後、新型弾道ミサイル開発に乗り出した。
しかし初の試射試験に失敗。
一方、北朝鮮は、新型4点セットの完成も間近で、既に大陸間弾道ミサイル（ICBM）の発射にも成功した。

South Korea:Two missiles were test-fired but one of them reportedly failed.
South Korea conducts first test launch of Hyunmoo-4 ballistic missile
The South Korean military
conducted in mid-March the first test-firing of its new Hyunmoo-4 (also spelled Hyeonmu-4) ballistic missile,
some two-and-a-half years after Washington and Seoul had agreed to scrap the warhead weight limit for South Korean missiles stipulated in US-South Korean guidelines.
A South Korean military official told Jane’s on 10 May
that the first test launch of the 800-km-range weapon, which features a greater payload than previous Hyunmoo-series missile systems,
was conducted at the Agency for Defense Development’s (ADD’s) Anheung test site in Taean County, South Chungcheong Province.
Two missiles were test-fired but one of them reportedly failed.
No information was provided about the cause of the failure.
The original US-South Korean ballistic missile guidelines of 1979 stopped the development of South Korean ballistic missiles.
A revision made in 1997
allowed South Korea to develop a ballistic missile carrying a 500 kg warhead with a maximum strike range of 300 km.
This missile, initially known as the Hyunmoo-2 (also spelled Hyeonmu-2), is now known as the Hyunmoo-2A.
A further revision of the guidelines in 2012
permitted Seoul to extend the range and/or payload of its ballistic missiles.
For instance,
it allowed for South Korean ballistic missiles to havea maximum range
- of 800 km while carrying a 500 kg warhead;
- of 500 km while carrying a 1,000 kg warhead;
- of 300 km while carrying a 2,000 kg warhead.
This changed, however,
after US President Donald Trump and his South Korean counterpart, Moon Jae-in,
announced on 7 November 2017 that they had finalised a deal to scrap the warhead weight limit for South Korean missiles.
As a result,the Republic of Korea (RoK) military
has since been looking to increase fourfold the payload of some its missiles, either by modifying them or developing new ones, said officials.
