Technology Highlights: Multi-engine Parallel Technology

Diameter: 3.35M
Length of fairing: 8m
Engine: 50t LOX/kerosene
Carrier Capacity: 4.5t @ LEO
Technical Highlights: Rocket Sub-stage Recovery and Reuse Technology

Engine specifications.

ShenlanThunder-Ⅰ
Vacuum thrust: 100kN
Sea level thrust: 88kN
Sea level specific impulse: 265s

Press release from Deep Blue Aerospace (in Chinese) http://www.dbaspace.com/newsthing_s.html?n_id=24
Extract
"While Deep Blue Aerospace is conducting a complete analysis of the data of this test, the "Nebula-M" rocket No. 2 test prototype is in the company's assembly plant in Nantong, Jiangsu, and is quickly undergoing assembly and testing. At the same time, the company will continue to implement 100-meter-level low-altitude flight and high-altitude vertical take-off and landing flight tests in 2021. At the same time, Deep Blue Aerospace’s main product "Nebula-1" into orbit rocket has completed the prototype production and strength test of a sub-level rocket body structure last year, and the orbital level launch and vertical recovery test will also be gradually implemented as planned."

Nebula-1 orbital launch vehicle now planned for first flight in 2023:

Deep Blue Aerospace conducts 100-meter VTVL rocket test [dated Oct. 13]

Quote
The test is part of the development of the 2.25-meter-diameter Nebula-1 orbital launcher, with a planned first flight in 2023. The Nebula-1 is to be capable of lifting 500 kilograms to a 500-kilometer Sun-synchronous orbit.

So is Nebula-M the test vehicle (not orbital) and Nebula-1 is the 500kg to orbit? Does the larger rocket have an announced name?

And is the first stage VTVL recovery just for the larger rocket or also Nebula-1?

It is expected that this prototype will be retired in order to continue with the full-size prototype which will perform flights of 10 to 100 km.

through iterative developments in future.  9 of the engines will be used in the 1st stage of orbital class rocket Nebula-1, which is expected to fly in 2023. It will be able to deliver 2000kg payloads to LEO, or 1000kg to 500km SSO.

Following the 1km hop test, DeepBlue completed a series of 5 hot fire tests of its newly developed Thunder-R1 reusable kerolox engine, lasting 4s, 7s, 7s, 30s, 90s respectively. The engine provides 15-tf thrust at sea level, 20tf in vacuum, with a goal of reaching 35-40 tf.....

Deep Blue Aerospace is preparing for their 4th VTVL test. It's their first VTVL test with actual orbital engines & real 3.35M sized vehicle. They plan to have an orbital launch & first stage recovery (vertically) in 2024. via mp.weixin.qq.com/s/y2juDUscVs05…
