We don't have a dedicated naval radar thread, or at least one that I can find. So I'm posting it here.


Cool catch. This is a navigation radar, so this is something you also expect all ships to use, not just warships. This includes everything including coast guard ships, and every type of commercial vessel.

It is also interesting to note the radar is using Gallium Nitride.

GaN in a surface navigation radar but still building mechanically scanning Type 382, etc.. That said, will be interesting to find out which other radars are using GaN and whether there is an upgrade program for existing AESA radars in the works.

If they are using GaN on a dual use radar that is also intended for commercial sale and use, its likely GaN has already found its way with military radars in the PLA, including the PLAN. However, they don't advertise it, though I deeply suspect the 055's radars are

But sometimes PLAN is a little slow and likes the tried and true. Bangladesh is already using SR2410C AESA on its corvettes but PLAN is still using old school mechanical radar on the Type 056A. Pakistan is also getting SR2410C AESA on 054A/P.

Type 382 mechanically scans only in the horizontal, but it is electronically scanning in the vertical. So 2D electronic scanning vertical + 2D mechanical scan in the horizontal, overall, gives a 3D scan. Frequency scanning radars of this type has been proven to be very cost effective and reliable in all these years. Nimitz, San Antonio, Wasp class, all uses frequency scanning radar, theirs is called SPS-48. Russian FREGAT which is where Type 382 is inspired from, has over 60 deployments on record. A good number of the PLA's ground radars are frequency scan, including the Type 305B which is used to support SAM batteries.

One thing Type 382 might be different from Fregat is that one side might scan with the S-band and the other side, the smaller side, might scan with C-band. So it works like a dual band radar, and this gives you the benefit of the two bands, the longer range with the S-band and the tighter angular resolution you get with C-band. Export AESAs like the SR2410C are single band only, the SR2410C is C-band only.

Compared to radars that are linear shaped like the previous post which are 2D only, or highly rectangular, which means primarily surface scanning with some elevation, the Type 382 gives equal attention to both air or vertical search and with horizontal or surface scan with equal proportions in the array width and height. Type 382 has a large number of elements in the vertical --- each line in the face is an element --- so this can give more accurate elevation information. The proper replacement for this radar is more likely like the new AESA one you see on the Type 075 which is dual backed and dual band. The Type 075 still has the Type 382 however.

Just to be clear this is still a 2D mechanically scanning radar. It only scans for horizon as it spins around. It may use GaN for receive and transmit, but it only has one element and that is the whole bar itself.

Chinese navy trains fighter pilots into aircraft carrier commanders

The Chinese People's Liberation Army (PLA) Navy is training jet fighter pilots to sail and command warships, a move that aims to create more capable commanding officers for aircraft carriers, according to military experts.

Experienced pilots from carrier-borne aircraft units and advanced fighter jet units started learning warship combat and command at an undisclosed naval academy in late November, the PLA Daily reported on Monday.

This is a whole new exploration by the navy to develop ship-aircraft command talent, as China's aircraft carrier force is in urgent need of such talent, the PLA Daily said, noting that the trainees were carefully selected, passing more than 10 tests including political thought, psychological quality and comprehensive abilities.

One such trainee is Xu Ying, chief of staff at an aircraft carrier-borne fighter jet base, who was among the first in the country to receive certification to operate a fighter jet on an aircraft carrier at both daytime and nighttime.

"During the training, I need to finish courses including ship navigation, basic combat, military training and management, strategic thinking and aircraft carrier combat," Xu said.

"I will gain the ability to command coordinated ship-aircraft operations by actually sailing warships and passing tests."

The training seeks to develop inter-disciplinary talent, as their experiences in both flying and sailing would work in synergy, Wei Dongxu, a Beijing military analyst, told the Global Times on Monday.

"I believe this is a move that aims to create top commanding officers for future aircraft carriers," Wei said, noting that this kind of talent would be practical in boosting the capability of carriers.

Many US aircraft carrier captains and officers at command posts used to be carrier-borne aircraft pilots, and this model is worth studying, Wei said.

Liu Zhe, captain of the Liaoning, China's first aircraft carrier, said on China Central Television in August 2017 that only the US required aircraft carrier captains to be pilots first due to the massive scale of its aircraft carrier fleet.

Liu said he was only a surface vessel officer and no pilot. He said he learned to fly trainer aircraft and helicopters, but only for a few hours.

"When we have more aircraft carriers in the future and more [carrier-based] pilots, as they grow older, there will be [pilots who become captains]," Liu said.

I would say this radar

Reminds me of the radar on the back of the Type 056A. They are made by CSSC and 724 is definitely a military designation. But linear arrays are also commonly used for marine radars.
