A thread detailing the speed, range and trajectory of China's anti-ship hypersonic missiles.

Our potential enemies have no way of intercepting these missiles, so it's only fair to let them know, how their billion dollar ship will be destroyed.
🧵 Image
YJ-17 Ship launched hypersonic glide vehicle. (HGV launched from vertical launch systems)

Range: over 1000km.
Warhead: 300kg
Cruise speed: Mach 5-8.
Terminal speed: Mach 8+

Launch trajectory; Boosted to 50km altitude, glide in the upper atmosphere, then dive down at Mach 8+. Image
Image
YJ-19 submarine launched Scramjet hypersonic missile.

Range: over 600km.
Warhead: 160kg.
Cruise speed: Mach 5-6.
Terminal speed: Mach 6+

Launch trajectory; Boosted to 20km, cruise at a flat trajectory at 20km, then dive down from above at Mach 6+. Image
Image
YJ-20, ship launched hypersonic anti-ship ballistic missile.

Range: over 1800km.
Warhead: 1000kg.
Cruise speed: Mach 10(ballistic).
Terminal speed: Mach 10+.

Boosted up to 150km+, outside of the atmosphere, reentry and dive onto ships, skewing them entirely. Image
YJ-21, air launched hypersonic anti-ship ballistic missile

Range: over 1200km.
Cruise speed: Mach 6.
Terminal speed: Mach 6+.

Air launched from 10km, boost then cruise at 30km, then dive onto targets. Image
China's entire anti-ship arsenal is moving into the hypersonic realm. Imagine hundreds of them flying towards our enemy fleet at hypersonic speeds.

Timed correctly with other subsonic stealthy missiles and torpedoes, no fleet defense in the world can stop our salvos.

How China's 4th gen tank exemplifies the differences in force design between China and the US?🧵1/8

The US military has global projection needs, their weapons are not specialized to do certain tasks in certain regions against certain enemies. It's a case of jack of all trade.

Meanwhile, China's ZTZ-201 light MBT is specifically designed to fight in Taiwan and the Himalayas.Image
Taiwan's useful terrain is very flat, dotted with cities and towns that are less than 2km apart.

Hence engagement even for armored/mechanized forces will be that 2km dash over farmlands then into cities.
Short engagements between tanks, if it ever happens, will be from covered position shooting at each other.

This means drones and sensor networks are more important than pure mass in armor. Image

Comprehensive minute-by-minute illustrative thread, on how the Chinese aircraft carrier Fujian conducts cyclical attack operation.
🧵1/15

The optimal air wing composition:
⏺️24x J-35(green & red), divided into 2 attack waves of 12 each.
⏺️24x J-15T (blue & purple), divided into 2 attack waves of 12 each.
⏺️4x J-15D electronic warfare fighter (orange).
⏺️4x J-600 AEW&C (light blue).
⏺️~10 helicopters (black) for anti-submarine, search and rescue missions.Image
Cyclical operations are the most common attack mode of aircraft carriers, they divide the carrier airwing into attack waves and launch them with intervals in between.

This allows sustained operation for a long periods of time. Image
🔹Wave 1 (green J-35 stealth fighters) takes 12 minutes to launch 12x J-35, + 2 min to launch 1x KJ-600 (light blue) + 1 min to launch 2x J-15D EW fighter (orange).
= 15 minutes.

**Catapults can launch aircraft with 30 second intervals.Image

A comprehensive thread about Chinese aircraft carrier operations.

How do we compare to the US aircraft carrier operations?

For the PLA navy, there are 2 main types of carrier attacks:
🔹Full-deck strike (Full deck sortie).
🔹Cyclical operation.
1/11🧵 Image
Full-deck strike is when we launch all fighters in a single strike package.

Cyclical operation is when we divide the fighters into attack waves, and launch them sequentially.

Full-deck strike is used when you want overwhelming firepower delivered in the initial phase of combat.
However, full-deck strike cannot be sustained for long, since all the fighters would need to land in a short span of time, which puts immense pressure on the deck crew to rearm and refuel.

The most important characteristics to 6th generation fighter is stealth.

6th gen stealth means, All-Aspect Stealth (stealthy from all directions) and Broadband (multi-spectrum) stealth.

What is it, how does it work?
1/8🧵 Image
5th gen stealth is achieved by aligning control surfaces to as fewer directions as possible, this edge alignment ensures radar signals are reflected back towards specific directions.

This is a simplified explanation without going into specular reflections or creeping waves etc. Image
Image
HOWEVER, the problem with 5th gen stealth is that they are detectable by low frequency radars with long wavelengths.

Resonant scattering is when radar waves interact with a target in a way that causes them to be scattered strongly, often at specific frequencies, due to the target's size and shape resonating with the radar's wavelength.

India will most likely procure the Su-57 to meet the challenges of Pakistan's J-35A supplied by China.

How does the 2 fighter compare?

An objective comparison between the J-35a and Su-57.
Thread🧵 Image
Image
🔹Stealth

From edge alignment to detail treatment, the J-35A is leagues ahead of Su-57, which has many protrusions and inconsistent surface treatment that are detrimental to radar stealth. Image
Image
Issues such as right angled seams, rounded engine protrusions, and the glaring "pimple" of an EOTS at the front, will all contribute to radar reflections. Image

It's June 4th, the anti-China shills are out of the woodwork for the "Tiananmen square massacre".

A thread of 1st hand video describing the incident:

1️⃣the photographer who took the famous Tank Man photo, he stated the protesters were the one who started killing soldiers:
1/7
2️⃣The PLA were RESPONDING TO a violent insurrection, where the so called protesters were armed with heavy weaponry.

They were NOT unarmed as western propaganda portrayed them.

Here the insurrectionists were firing a heavy machine gun.
3️⃣The PLA showed maximum restraint, because we are the army of the people.

However, these are not the people, they are the enemies of the people.

Watch how the PLA units refused to open fire, despite our comrades were being stoned to death.

This in retrospect were an mistake:
