Chinese researchers have reportedly demonstrated a swarm of 116 autonomous underwater vehicles (AUVs) operating simultaneously, setting a Guinness World Record.
The TH-618 vehicles reportedly operated for approximately 34 minutes and covered nearly 500 m (1,640 ft) along a designated route while maintaining formation and coordinating their movements with minimal operator control.
The TH-618 is approximately 61.5 cm (2 ft) long and is reportedly capable of operating for more than eight hours and traveling up to 30 km (18.6 miles).
Underwater swarms face communication and navigation challenges because GPS is unavailable underwater and radio signals are rapidly attenuated. The reported demonstration involved local navigation and distributed coordination between the vehicles.
Such systems could reportedly be used for seabed surveying, object searches and inspection of underwater infrastructure.

من همچنان روی Stunner Block-3 که تصویر کوت شده باشه شک دارم،دو جستوگر EO و RF در نسخه All weather نمیتونه کنار هم باشه(مزاحم دید سیکر،مزاحم حرکت مکانیکی و جاگیری آنتن سیکر).
بیشتر حدس می زنم نسخه اپدیت شده Block-2 در تصویر کوت شده باشه.

On Thursday, an airstrike killed 3 a mom, a dad, and their 2-year-old son on Qeshm Island in southern Iran.
Our visual investigation (drawing on photos/videos from the site, satellite imagery, weapon fragments, and a crater size estimate, analyzed by weapons experts @Easybakeovensz @fredgrs) indicates the U.S. dropped one of the largest bombs in regular use by its military on the residential neighborhood: the Mark-84, a 2,000-pound bomb.
The choice to use that type of munition in such a densely populated area is “very difficult to reconcile with” the obligation under international humanitarian law to take all feasible precautions to minimize civilian harm, @tomdannenbaum told us.

The Israeli Army recovered Hezbollah devices labeled “J-AHMINE” that resemble the Iranian “YM-J-AHM2” anti-helicopter bounding landmine.
Upon activation by a wired connection or radio receiver, the mine body jumps up to 250–300 meters and detonates, scattering 8 mm fragments.

A Spanish firm just proved its drone-killing interceptor works — not in a video render, but in live military tests in Slovakia.

This peculiar mortar shell fragment was recovered by an AFNM fighter in Dera district, North Shewa zone. Its red base is stamped CHEDDITTE 12 which is an Italian shotgun hull manufacturer. Is the Ethiopian army buying components from Italy? There are also OLA militants who launched a large scale abduction in Dera since June 16. I wonder if it was dropped from a drone? @criticalthreats
The regime forces used a Pakistani-made 60mm mortar round ML60 C11, to shell and disrupt a peaceful meeting between local farmers and AFNM leaders in Ensaro district on May 5.
The mortar attack caused injuries and destruction of property. @HammerOfWar5 @war_noir

The 🇺🇸 Army took delivery of an unspecified number of M98A3 LWCLUs last month. These will begin replacing the older Block 1 CLUs, and are compatible with Block 0 and Block 1 missiles, and the current prod FGM-148F. Unclear if the M98A3 and FGM-148G will from the future Block 2...

A fragmentation warhead from a Ukrainian RZ-60 strike UAV has two pathways to detonation.
A pair of EDP-r electric detonators allows command detonation for airburst or self-destruction.

1/? These are M4000 binary Sarin bombs.
The two precursors for Sarin (isopropyl alcohol and methylphosphonyl difluoride) would be loaded separately into the two holes in the side of the bomb. Inside the bomb are two chambers separated by a membrane.
#Syria: the Organisation for the Prohibition of Chemical Weapons (OPCW) found 54 aerial bombs used to disperse chemical agents.
They are of a similar model to those used in Lataminah attack in 2017.
25 rockets like those used in the E. Ghouta sarin attack in 2013 were also found.
Munitions, equipment and chemical stockpiles were transferred to special facilities in preparation for their destruction.
