On April 2nd, the AN/SPY-7(V)1 radar, designed for Japan's future Aegis System Equipped Vessels (ASEVs), showcased its capability to track targets beyond Earth's atmosphere for the first time. This radar is crucial for ASEVs armed with SM-3 anti-missile interceptors, which target ballistic missiles during their mid-course flight phase. The ASEVs, resembling cruisers, will also possess Tomahawk cruise missiles, enhancing Japan's long-range strike capabilities. The US Missile Defense Agency confirmed the successful test, conducted on March 28, at Lockheed Martin's Production Test Center in New Jersey. The ASEVs, expected to enter service in 2028 and 2029 respectively, will cost around $2.7 billion each. With 128 Vertical Launch System cells, the ASEVs will accommodate SM-3 and SM-6 missiles, bolstering ballistic missile defense and engaging diverse air and missile threats. Plans include installing high-energy laser weapons to counter aerial drones. Tomahawk integration signifies Japan's expanded strike capabilities, aimed at targets over 1,000 miles away, supporting its stand-off defense strategy. These ASEVs will contribute to Japan's integrated air and missile networks, enhancing missile defense coverage and bolstering US-Japan cooperation. Overall, the ASEVs represent a significant advancement in Japan's maritime defense capabilities, integrating advanced radar technology and a versatile weapons suite.

On April 3rd, North Korea announced the successful test of a new hypersonic intermediate-range missile fueled by solid propellants, escalating tensions in the region. Kim Jong Un claimed the capability to develop solid-fuel, nuclear-capable missile systems of all ranges, enhancing North Korea's nuclear deterrent against perceived threats from the US, South Korea, and Japan. The missile launch, supervised by Kim, marks North Korea's advancement in solid-fuel technology, making missiles more mobile and quicker to deploy. North Korea's arsenal includes solid-fuel intercontinental ballistic missiles and a variety of short and mid-range missiles, some demonstrated in simulated nuclear strikes. Recent tests also include hypersonic weapons, potentially challenging regional defense systems. While North Korea claims successful tests, the consistency of achieving hypersonic speeds remains uncertain. Tensions heightened since 2022, exacerbated by Kim's accelerated missile testing amid international distractions. In response, the US and allies conducted joint exercises, showcasing strategic assets in the region. North Korea, meanwhile, vows to expand its nuclear and missile programs, seeking overwhelming power against perceived adversaries.

On April 4th in the Red Sea, the Navy destroyer Gravely and US forces intercepted and destroyed an anti-ship ballistic missile and two drones launched by Houthi militants in Yemen. Additionally, a mobile surface-to-air missile system in Houthi-controlled territory was neutralized. There were no reported injuries or damage to US, coalition, or commercial ships. This engagement follows the Houthis' recent attempts to target US warships with drones. US officials discussed the ongoing conflict and the importance of achieving maritime security in the region. Lt. Gen. Alexus Grynkewich suggested the Houthis may be depleting their supplies of drone swarms and missiles. US Special Envoy for Yemen, Tim Lenderking, emphasized the necessity of a diplomatic solution to de-escalate the situation, noting that while terrorist designations may pressure the Houthis, a military resolution is not feasible.
