Der neue 3D-gedruckte Feststoffraketenmotor von Ursa Major schließt den Flugtest erfolgreich ab

From the article

>A long-range solid rocket motor (SRM) developed by rocket engine manufacturer [Ursa Major](https://www.ursamajor.com/) and Virginia-based [Raytheon Technologies](https://www.rtx.com/) has completed successful missile flight testing for the [US Army](https://www.army.mil/). The motor has so far been flown twice with Raytheon at Naval Air Weapons Station China Lake.  

>Ursa Major’s Lynx 3D printing technology was used to manufacture the SRM. This, in combination with Raytheon’s digital engineering capabilities, enabled the partners to accelerate development times and cut production costs. 

>Daniel Jablonsky, Ursa Major’s CEO, explained that the firm has utilized additive manufacturing to achieve “unprecedented timelines,” with nearly 300 SRM static test fires completed in 2024 alone. For this latest project, the team went from concept and design to firing and flight in under four months, which Jablonsky called “lightning fast.” He added that 3D printing has facilitated the production of “agile solid rocket motor solutions with the design flexibility needed to expand the capabilities of the US military.” 

>In the US, demand for SRMs is coupled with a shortage of domestic suppliers. Supply chain challenges are impacting the [US Department of Defense](https://www.defense.gov/) (DoD)’s efforts to restock inventories and support ongoing war efforts in Ukraine and Israel. The Pentagon’s annual budget request for missile and munitions procurement, as well as related research and development, increased from $9 billion in 2015 to $30.6 billion in 2024.
