The small thrust of the second stage is probably due to the fact that the payload is launched into orbit by one (but not two) engine actuations. In this case, the optimal thrust of the second stage may be ten times smaller than the thrust of the first stage.
BW-0.3 hover test. Will be followed by the development of upper stage named BW-0.4 and first stage named BW-0.6.

https://www.mk.co.kr/en/it/10988022Reports that Perigee Aerospace may be targeting a May 27th test of its vehicule (I've heard it may more likely be a sea-launched test of the second stage, BW-0.4, instead of the first stage), the article says it is an orbital test?
"Meet Cetacea 1, our marine launch platform. Stay tuned for its first mission: BW0.4 launch. "

On the 23rd, Perigee Aerospace announced that it will tentatively launch Blue Whale from Jeju on the 27th of next month, at the latest within the first half of this year. The launch will use ‘Setesia 1’, a Perigi Aerospace marine launch platform, in the west sea of Jeju. The plan is to launch Blue Whale from a launch pad located at sea, perform a suborbital flight, and then drop it to the sea level within a safety control radius. Perigee Aerospace said, “This launch will verify the flight capabilities of Blue Whale, which we developed ourselves. If the launch is successful, it will mean that the performance and stability of the propulsion, structure, and flight control systems of the launch vehicle have been verified.” explained.This launch will also carry a payload. It will be launched carrying micro-satellite components from domestic space company Cairospace and Spacelintech's space medicine platform. Perigee Aerospace said, “In addition to verifying the launch vehicle, we will also verify the space technology of domestic New Space companies.”
SSC and South Korean rocket company Perigee Aerospace Inc. have signed a collaborative agreement to launch satellites jointly from Esrange Space Center in northern Sweden, starting 2025. Perigee’s Blue Whale 1 microlauncher will be the first-ever orbital rocket launched from Esrange.
