The RX rocket family (Roket Eksperimental) is a series of solid-fuel rockets developed by the Indonesian National Institute of Aeronautics and Space. They are simply named by their diameter in millimeters; for example, the RX-250 has a diameter of 250 mm.[1]

Notes	Characteristics in italics are design values, they have not been measured yet.

RX-250 was launched eight times from 1987 to 2007.[4] RX-320 was launched twice in 2008[4] and once again in 2014.[5] RX-420 flew just once in 2009; it is superseded by RX-450 which was launched on 13 May 2015[6] As of May 2016, the next booster version RX-550 is under construction; the larger ones are only on the drawing board.

Multi-stage rockets

Once the solid boosters are fully qualified, LAPAN plans to assemble several of them into multi-stage rockets called Roket Pengorbit Satelit or RPS. Four staging configurations have been retained so far:[7]

RPS-01 Variant 1 (ex-RPS-420)

First stage: 3 x RX-420
Second stage: 1 x RX-420
Third stage: 1 x RX-420 (shorter)
Fourth stage: 1 x RX-320
Total height: 10.00 m

RPS-01 Variant 2b

First stage: 1 x RX-550 + 2 x RX-420
Second stage: 1 x RX-550
Third stage: 1 x RX-320
Total height: 15.75 m

RPS-01 Variant 3a

First stage: 1 x RX-450
Second stage: 1 x RX-450
Total height: 10.75 m

RPS-01 Variant 3b

First stage: 1 x RX-450 + 2 x RX-320
Second stage: 1 x RX-450
Third stage: 1 x RX-320
Total height: 11.75 m

Earlier plans for the Pengorbitan-1 and -2 orbital launch vehicles (RPS-420s) were based on the RX-420 engine which was superseded by the RX-450. As of May 2016, integration work is proceeding on variants 3a and 3b, whose engines have all been successfully flight-qualified.

Since 2019, LAPAN's rocket division PUSTEKROKET has collaborated with AASPT and CGWIC of China in designing newer multiple stage sounding rockets. The new rocket will be called RX-452 which combined 400 mm diameter 1st stage with 450 mm diameter 2nd stage. The design is based on TK-32 sounding rocket as well as RX-450. It is expected the newer design to be able to reach above 100 km, simulation showed the rocket is able to reach 200 km. [8]

RX-452

First stage: 1 x RX-400
Second stage: 1 x RX-450
Total height: 8.6 m

gollark: That would make it explicitly net negative.

gollark: There are three outcomes, roughly:- it is fair, you win: you gain the total money- it is fair, you do not win: you lose what you spent- it is biased/evil/infohazardous and you lose money: you lose what you spent

gollark: We can calculate the expected value of this quite easily.

gollark: I think ALL are to not participate.

gollark: Or what the owner might do with the private key, even.
