China Builds Mother Ship for Deep-Submergence Vehicle



The ship, "Zhang Jian", named after the founder of Shanghai Ocean University, is 97 meters long and 17.8 meters wide. It has a designed displacement of around 4,800 tons and 15,000-nautical mile endurance ability, Xinhua news agency reported.

Designed to carry 60 people, the ship will boast advanced laboratories, data processing and information centers and other devices.

The "Zhang Jian" will serve as a mother ship to the manned submersible "Rainbow Fish" which is capable of diving to a depth of 11,000 meters, and will be used in general ocean expedition missions, deep-sea engineering, rescue and salvage, underwater archaeology and film shooting, said Cui Weicheng, head of the Hadal Research Center at Shanghai Ocean University.

The vessel is scheduled to float in June 2016. Chinese scientists will launch unmanned diving expeditions in the deepest area of the Pacific's Mariana Trench in 2016, and manned diving in this area in 2019, with the Rainbow Fish submersible and other deep-sea devices, the agency said.

China's manned submersible “Jiaolong” reached its deepest depth of 7,062 meters in the Mariana Trench in June 2012.

Iran Rolls Out New Programmable Drone



"Basir is a self-control drone that moves according to the flight plan in the specified routes and land in the same take-off point after ending its mission," an official of the Northwestern city of Zanjan's 216 Armored Brigade Mohammad Mohammadi said Saturday, Fars news agency reported.

The new aircraft is designed to gather samples from areas contaminated with chemical materials and keep an eye on areas afflicted with natural disasters.

In addition, Basir can be armed with different weapons to be used for other missions such as street wars, reconnaissance and surveillance missions.

Iran also boasts a fleet of the so-called fire-and-forget drones. Like, for example, the indigenously-made Ra'd (Thunder) 85 which can be reprogrammed to destroy specific and changing targets hundreds of miles away with maximum precision, a ground force commander said.

Fire-and-forget is a type of missile guidance system that does not need to be guided after launch by such techniques as marking the target or wired guidance; these systems can hit targets without the launcher being in line-of-sight of the target.

The Islamic Republic plans to ramp up the number of its home-made drones within the next five years, and operate long-range ones for very distant missions.

Iran is one of the five manufactures of Unmanned Aerial Vehicles (UAVs) in the world, western media reports said in February.

The other four are the US, Russia, China and Israel.

hehe dah tahu cerita tu

dah discuss during golf session?

no news yet mean choices are still open.

But there already indication or giveaway what type of heli is being sought after
The new gowind deck been extended as well as its hanger. Meaning, the navy is looking for a bigger asw than the current fennec/lynx

seahawk?

Actually it was designed to fit in both uav and asw heli.
Though the budget not enough to cover uav in the end.

there NH90, there AW101 (which might be actually overweight)

10ton deck limit

Gowind in ori design already can fit NH90 size 10 tons heli, so no issue fit seahawk or NH90. even can add 1 more S100 uav for our Gowind

hehe the UAV already knew long ago most likely wont be funded

that after ours, the 2500 is based on our requirement technically

Seahawk is good, very capable asw platform for the gowind

Still better than anti sub mortar if you ask me.

ASW torpedo range is too short. Unless it is launch from a helicopter, or rocket boosted like the ASROC or the Stallion, it won't be much use against modern Submarine. BTW, why not we get the ASROC. The latest version is vertical launch. I'm sure it can fit inside the Gowind VLS cell.

Nope.. unless we use mark 41 vls i doubt we can fit it onto slyer vls

I was told once that depth charge is more effective on shallow water because sub cant dive further down to hide.

Maybe LTZ can give better insight

Deep charge is quite gooding on shallow water.
saab asw 601 was my favourite.
Can easily install on small ship, low cost and darn easy to reload.

Asroc would be nice but

I looking more toward MILAS system based on MU90 and otomat missile. And since we operate the otomat missile system should not be a problem for future training.

The only things is whre put. A very big system unlike vl-asroc can put onto vls

The lack of range is still an issue. I doubt any half competent sub driver would allow his sub to get that close to an enemy ship. He would've keep it within his arm's length.

Once a submarine lauch a torpedo. That when it most vunerable because it basically tell the enemy that he is there and within close proximity which also can be calculated.

No matter how advance a torpedo is.. a closer engagement range give better hit sucess. Trial and tested since ww2. Plus, even mordern sop based on us subs is to get visual first then only lauch torpedo to avoid shooting the wrong ships and also visual confirmation of the kill.

For ship defence.. there decoys and if decoys fail anti-torpedo torpedo. The milas or asroc is more toward hunting the subs once the ship successful defend itself from torpedo hit.
