I found some details on this page. https://historia.id/sains/articles/...t-mewabah-6jo95 Of course, I don’t know Indonesian, but with a translation software, I was able to find some historical information. Kartika rockets were built for the 1964-1965 IQSY. They were 250 mm in diameter, weighed 220 kg and could climb to an altitude of 60 km. The first was launched on 14 August 1964 and the second in November 1964. The Indonesian government decided to import 10 Japanese Kappa 8 rockets because the scientific programme had fallen behind. Three were launched in August 1965, as we have seen. The other seven Kappa 8 rockets were never launched because of the events of September 30, 1965. |

I like the clipped-delta fins. Also interesting they put a military roundel marking on the fins - adds a little color!

Great information . . .
In addition to the length of 10.5 m ( my post ), your data provides a diameter of 250 mm. Everything I found said that only 1 rocket was built and flown ( those color displays are down-sized replicas for display ) . . . It was called "KARTIKA I". Thanks for the additional info ! Dave F. |

If I look closely at the photos you posted, I don’t think the Kartika rocket was 10.5 m long. I think it was the length of the Kappa 8 rocket. Kartika seems to measure about half of this length. Here is another photo, unfortunately small. |

Interesting . . . I, initially, thought that the color photo's I posted were of scaled-down, display rockets. However, if you are correct, then they could be full-size. Take a look at the scale of objects, relative to the rocket, in the attached images. Dave F. |

I just found a new photo on this page https://aviahistoria.com/2021/06/10...atan-indonesia/ If you compare the size of the rocket with the size of the soldier using the marks on the launch ramp, I don't get the impression that the rocket is over 6 m (20 feet) high. |

Great idea to use the rail as a reference point ! CAUTION - The spacing of those "ribs" on the rail are not uniform. The lower "ribs" appear to be spaced about 24" apart. The spacing gets wider, higher up the rail. The soldier in the light colored uniform has his left foot on the ground and his right foot on the platform base - about 4"-6" higher . The second soldier is standing on the platform. The average height for an Indonesian man is 5', 2.25" http://chartsbin.com/view/38919 Thr rocket, of course, is not on the rail in that photo.

You’re right about the spacing between the "ribs". It’s about 10% larger from the fifth one. Despite this, if we consider that the average size of the people in the photo is 1.60 m, the height of the rocket must be between 5 and 6 meters. In any case, I don’t see how it could exceed 10 meters. What is your opinion? |

Agreed . . . So, with a known diameter of 250mm for the Booster and a "range" for overall length, scaling photo's should allow for making dimensioned drawings and building a decent model ! Based on what has been discovered, the "10.5 m" overall length data can be dismissed, as erroneous, in my opinion. Dave F. |
