How the CCRP functions in a attack run:


Function during Dive Bombing

Before the attack, the pilot sets the attack type (level or dive), weapon type, estimated air pressure at the target, wind speed and direction, and the aircraft’s estimated gross weight. During the approach, the gyros are levelled, and the system confirms when the gyros are free. The release button is armed. Using the reflex sight, the pilot aligns the aircraft with the target in level flight at a shallow dive angle, typically between 5-30 degrees. The system confirms that the aircraft is within the sight’s operational range. When the release position is achieved, the release button is pressed, initiating a gentle pull-up. The release button is held down until the pull-up is completed. The sight automatically calculates the correct release timing for the bombs.

Function during Rocket Firing

Rocket firing is conducted during a dive towards the target. The pilot only needs to stay roughly within the prescribed firing range for each type of rocket. The sight automatically accounts for the aircraft’s speed and dive angle.

Figure 1. Reflex sight K-14 with accessories

The reflex sight is located in front of the pilot and has two optical systems that provide a fixed and a movable sight picture. The control box, located to the right of the pilot, is used to adjust the brightness of the sight pictures and to select the desired sight picture(s). When using the BT9 bomb sight, only the fixed sight picture is used, and the control box’s adjustment knob is set to FIXED. In the FIXED & GYRO position, both sight pictures are visible, and in the GYRO position, only the movable sight picture is displayed."

Also, the French Etendard and Swiss Hunter F.Mk.58 have the BT-9 installed. See detailed bug report on missing BT-9 on the Hunter here: Hunter F.58 missing BT-9 bomb computer // // Issues


I live relatively close to multiple Swedish Armour And Aviation Archives & Museum’s , Therefor I can easily find thing such as these with ease and with me living in Sweden I get Multiple results for things such as these without much digging. These Museums around me have been great help suggesting websites and even first hand documentation of Erik Wilkinson’s diary when developing the SAAB BT- (2-3-9 sights) Also his documentation of the research and production of the: Saab B17, Saab B18, Saab J21 etc. its a long book. i have it downloaded as a PDF File its in Swedish though so translation has to be done with AI mostly if i want other people on here to understand it.
