Hello!
Your post has sparked my interest to research about this new sounding rocket.
I couldn't find how the last rockets were transported from Brazil to Sweden, and therefore if the air transport with the A400M was an extraordinary measure or not.
Anyway, I find the Red Kite rocket developments very interesting. The best source I found was this paper:
https://elib.dlr.de/197879/1/2022_06%20Scheuerpflug%2C%20Kuhn%20et%20al.%2C%20%20Development%20and%20Performance%20of%20the%20Red%20Kite.pdfIt includes detailed information about the rocket motor and the possible launch configurations. They include a possible combination with a Black Brant Mk4 as a second stage.
About the Red Kite it is a new design, kind of as big as the S30 but with the quick burn rate of the S31 (and quite more powerful than it).
The performance seems quite good, specially in combination with an Improved Malemute second stage (even better than VSB-30 [S31+S30]).
I found the data about these missions launched from ESRANGE:
- Texus 59 - VSB-30 - payload mass: 388.0 kg - Apogee: 264.5 km
- Mapheus 14 - RK-IM - payload mass: 442.8 kg - Apogee: 265.2 km
It may be able to replace de VSB-30 completely.
Recently, it was announced that the production of Patriot PAC-2 missile will be restarted in Germany. Therefore, it will be possible to buy newly made Improved Malemute rockets.
