US Navy tests first AN/SPY-6(V)4 naval radar in Hawaii to improve ship defense against new threats

On August 26, 2025, Raytheon, together with the U.S. Navy, conducted the first live maritime test of the AN/SPY-6(V)4 radar at the Pacific Missile Range Facility in Barking Sands, Hawaii. The test took place at the Advanced Radar Detection Laboratory and involved multiple trials conducted over open water. During these events, the radar tracked both air and surface targets under a variety of conditions, and the demonstrations produced the first live data set for the (V)4 configuration. This dataset will be used to refine the radar for additional trials and eventual shipboard deployment, transitioning the program from years of laboratory work and simulations into operational validation. This marks the first time the (V)4 variant has been tested in a maritime environment, representing a step forward in its development path. Read full defense news at this link...

The AN/SPY-6(V)4 is a four-face S-band active electronically scanned array (AESA) radar designed to replace SPY-1 on in-service Arleigh Burke-class Flight IIA destroyers under the DDG MOD 2.0 program, which also includes other sensor and combat-system improvements. (Picture source: Raytheon)

US Navy considers Ford-class aircraft carrier redesign to match Trump's WWII island style preference

On August 16, 2026, the U.S. Navy initiated an operational and technical evaluation regarding whether to move the island superstructure on future Ford-class aircraft carriers from its current far-aft placement toward amidships, following directive preferences from President Donald Trump. The assessment will likely focus on whether relocating the command structure toward a World War II-era configuration would negatively impact flight deck operations, sortie generation rates, and recovery airflow dynamics. This design review also follows an August 13 directive ordering the Navy to replace the Electromagnetic Aircraft Launch System and Advanced Weapons Elevators on the future USS Doris Miller with steam catapults and hydraulic systems.  Read full defense news at this link... The USS Gerald R. Ford (CVN-78) places its island much farther aft so more aircraft can be parked and moved directly toward the catapults without interfering with landings, whereas USS Enterprise (CV-6)'s amidship...

Bath Iron Works starts building new Arleigh Burke-class Flight III destroyer USS J. William Middendorf

General Dynamics Bath Iron Works has started construction of the future USS J. William Middendorf (DDG 138), a Flight III Arleigh Burke-class destroyer that will strengthen the U.S. Navy’s missile-defense and escort capacity during sustained operations in the Red Sea, Eastern Mediterranean, and Indo-Pacific. The ceremonial first steel cut took place in Maine on May 19, 2026, as the Navy continues relying on Flight III destroyers equipped with the SPY-6 radar and Aegis Baseline 10 combat system to replace the air defense and command role of retiring Ticonderoga-class cruisers ahead of the future DDG(X) program.  Read full defense news at this link... USS J. William Middendorf belongs to the Flight III configuration that began with USS Jack H. Lucas (DDG 125), the first Flight III destroyer commissioned in October 2023.

China’s PHL-191 MLRS Shows How Airburst Munitions Could Transform Modern Battlefield Suppression

 China has showcased what appears to be an airburst-capable munition fired from its PHL-191 long-range modular multiple launch rocket system during a live-fire exercise, highlighting a growing emphasis on suppressing dispersed battlefield targets rather than relying solely on point strikes. Footage released on July 19, 2026, by China Military Online and the Chinese Ministry of National Defense suggests the PLA is expanding its long-range fire-support options with effects designed to disrupt troops, air-defense sites, and lightly protected equipment across a wider area, reinforcing its ability to shape the battlefield before major combat operations begin.  Read Full Defense News At This Link.
