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.
و نسخه RF این تصویر باشه:

Jet-Powered JDAM Production Is A Go For The U.S. Navy

Putting JDAM-LR into production will give the Navy an important new stream of lower-cost standoff munitions for its carrier air wings.

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.

Serbian Air Force finally unveiled all of the a-a and a-g weapons that the upgraded MiG-29 SM+ can employ.

Today also marks 10 years since the beginning of the SM+ upgrade project.

Two birds were displayed, one in the a-a and the other in the a-g config.

NEW REPORT from @SmallArmsSurvey and @SudanHSBA on illicit MANPADS in Sudan. We found that the Rapid Support Forces have at least 8 different models of MANPADS in their possession, including 5 advanced systems - the most of any group in the MENA region.https://t.co/IsQgpc7tqP

Rare VG-40TB and VZG-25 seen in use by russian drone units, likely turning it into drone ammunition soon.

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 🇺🇸 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...

@MSchroeder77 Does someone knows what is circled red hereunder. I was thinking its a charger for Manpads battery, but don't really know what it looks like....

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.
