The Vulcan rocket checks off a number of vital containers for the Area Power. First, it depends totally on US-made rocket engines. The Atlas V rocket it’s changing makes use of Russian-built fundamental engines, and given the chilled relations between the 2 powers, US officers have lengthy desired to cease utilizing Russian engines to energy the Pentagon’s satellites into orbit. Second, ULA says the Vulcan rocket will finally present a heavy-lift launch functionality at a decrease price than the corporate’s now-retired Delta IV Heavy rocket.
Third, Vulcan supplies the Area Power with a substitute for SpaceX’s Falcon 9 and Falcon Heavy, which have been the one rockets of their class accessible to the navy for the reason that final nationwide safety mission was launched on an Atlas V rocket one yr in the past.
Col. Jim Horne, mission director for the USSF-106 launch, mentioned this flight marks a “fairly historic level in our program’s historical past. We formally finish our reliance on Russian-made fundamental engines with this launch, and we proceed to take care of our assured entry to area with at the least two impartial rocket service corporations that we are able to leverage to get our capabilities on orbit.”
What’s onboard?
The Area Power has solely acknowledged one of many satellites aboard the USSF-106 mission, however there are extra payloads cocooned contained in the Vulcan rocket’s fairing.
The $250 million mission that officers are keen to speak about is called Navigation Know-how Satellite tv for pc-3, or NTS-3. This experimental spacecraft will take a look at new satellite tv for pc navigation applied sciences which will finally discover their means on next-generation GPS satellites. A key focus for engineers who designed and can function the NTS-3 satellite tv for pc is to have a look at methods of overcoming GPS jamming and spoofing, which might degrade satellite tv for pc navigation alerts utilized by navy forces, industrial airliners, and civilian drivers.
“We will be doing, we anticipate, over 100 completely different experiments,” mentioned Joanna Hinks, senior analysis aerospace engineer on the Air Power Analysis Laboratory’s area automobiles directorate, which manages the NTS-3 mission. “A number of the main areas we’re —now we have an electronically steerable phased array antenna in order that we are able to ship greater energy to get by means of interference to the situation that it is wanted.”

GPS jamming is particularly an issue in and close to battle zones. Investigators probing the crash of Azerbaijan Airways Flight 8243 final December decided GPS jamming, possible by Russian navy forces making an attempt to counter a Ukrainian drone strike, interfered with the plane’s navigation because it approached its vacation spot within the Russian republic of Chechnya. Azerbaijani authorities officers blamed a Russian surface-to-air missile for damaging the plane, in the end resulting in a crash in close by Kazakhstan that killed 38 folks.
“We now have a lot of completely different superior alerts that we’ve designed,” Hinks mentioned. “A kind of is the Chimera anti-spoofing sign… to guard civil customers from spoofing that’s affecting so many plane worldwide at the moment, in addition to ships.”
The NTS-3 spacecraft, developed by L3Harris and Northrop Grumman, solely takes up a fraction of the Vulcan rocket’s capability. The satellite tv for pc weighs lower than 3,000 kilos (about 1,250 kilograms), a couple of quarter of what this model of the Vulcan rocket can ship to geosynchronous orbit.
