The B-21 Raider has flown and we have finally been able to see all sides of this sixth generation bomber, including the rear aspect, which has, until now, been hidden from view. If you're an aviation enthusiast or you simply want to be a part of history unfolding, there is a lot to unpack here. Let's take a look at what the Raider's first flight reveals to us and why our adversaries should be concerned. One of the more unexpected features of the prototype B-21 Raider serial number 0001, is that it has a name. Yes, the aircraft that took flight last Friday is, of course, a B-21 Raider, but thanks to some excellent photography by Point Mugu Skies, we can see that this aircraft has been named Seribus. This is no accident. If you recall from your Greek mythology, class Seribus, or the hound of Hades, is the multi-headed dog that guards the gates of the underworld to prevent the dead from leaving. This naming is very fitting, as the B-21 may well end up being the aircraft with the most destructive flying potential ever.
Speaker 1:
As mentioned, the rear aspect of the Raider has been hidden from view until this flight and fortunately it fits in the flight profile that we were hoping for on this channel. Specifically, the plan form is optimized for high altitude flights. If you remember the development of the B-2 Spirit, initially the B-2 was supposed to have the same rear plan form, but there was a somewhat last minute requirement that the B-2 needed to fly low level missions. This caused the bomber to go through extensive redesigns and, of course, massive cost overruns. In the end, the B-2's rear section has a sawtooth look to it which allows it to fly at lower altitudes. Now that we've seen all sides of the B-21 Raider, it looks like the low level flying requirement was not part of the design for this new bomber, which is a good thing. Additionally, observers watching and recording the bomber's first flight also noticed a long trailing wire an aerial being towed by the B-21 as it flew by. Although this apparatus is the source of much speculation, these wires are normal for initial test flights and are used to capture undisturbed air or static measurements as the aircraft flies through the air. Along with this, at the front of the aircraft, there is a long Flight Test Air Data Probe which measures, among other things, the ram air moving into the aircraft, similar to the way that a P2 works on all airplanes. There are, of course, numerous other sensors installed all over the aircraft that we can't see. Suffice it to say that CERBUS 1 is a flying super server with untold number of sensors recording everything as the jet flies through the sky.
Speaker 1:
One of the biggest improvements from the B2 Spirit, of which, of course, the B-21 is based on, are the air inlets for the engines. Since the inlets have to protrude from the top of the airframe, they can be a source of detection by enemy radars. What the B-21 designers have done is make these inlets as low profile or conformal to the flying wing as possible. Apparently, flying wings do not have fuselages. It's all really just a single wing, for all components, including their cockpit, housed in the main wing structure.
Speaker 1:
Getting back to the air intakes, while lowering their profile is beneficial to reducing radar cross section or RCS, to avoid detection, the lower intakes do raise some challenges, the first being what is known as boundary layer air. Many modern aircraft, and especially stealth ones, use an S shaped or serpentine duct to hide engine fan blades from radar. The fan blades on a turbine engine are essentially perpendicular to the airflow and, as a result, is like a large mirror for detection radars. Basically, if exposed, these fan blades can turn into a giant windmill. Saying here I am to the detection radar. Because of this, airplane designers create convoluted air tunnels to keep feeding the engine vital air, while hiding these blades from outside view.
Speaker 1:
Lowering the intakes on the B-21 causes even more challenges as you start to approach the point at which not enough air is entering the engine. Keep in mind we're just talking about level flight. Things get interesting when the aircraft is flying supersonic or the aircraft is pitching up during moments like takeoff, climb and even landing. These higher pitch flight regimes introduce high angle of attack or high alpha, and can limit even further the amount of air being delivered to the engines. In the case of the B-2 Spirit, to overcome this it uses butterfly inlet doors that open up to allow air entering during these moments of high alpha, or other flight regimes that can restrict air flow into the engines. The B-21 Raider appears to follow a similar strategy by using large triangular doors that open up to allow air flow into the engines, which interestingly, give the Raider horns or a devilish appearance, which could be another reason.
Speaker 1:
The first jet has been named Sarabas. It is almost difficult to understate how important keeping the height of these inlets as low as possible is. You could argue it is the biggest factor in determining how stealthy the Raider ends up being. It's that critical. And speaking of the engines, we still, as of the making of this video, do not know the type or even number of engines the Raider has, but given its size, it seems very likely that the B-21 has two engines, even though early speculation called for four engines. Ultimately, we'll just have to wait and see.
Speaker 1:
Another area of the bomber we were able to look at, which we haven't seen before, was the belly. We can now clearly see the apparent single weapons bay which, given the B-21's smaller size as compared to the B-2. The weapons bay is smaller and almost definitely has less capacity than the larger B-2. Then there is the question as to what weapons the B-21 Raider will be able to carry and employ. One of the largest, the GBU-57B massive ordinance penetrator or MOP great acronym, by the way is the world's most powerful conventional bunker buster, designed to take out underground targets, literally buried under mountains. This 30,000 pound bomb can only be carried by a few aircraft Today, the B-2 Spirit can carry two, while the smaller B-21 can only likely carry one. However, the weapons bay will be designed to be smarter, meaning the ordinance packages will take advantage of the B-21's open architecture systems so that new weapons, new configurations of weapons and even air-launched drones can be employed by the Raider.
Speaker 1:
What we still don't know is whether the B-21 will have secondary weapons bays, like we've seen in both the F-35 Lightning and the F-22 Raptor. In both these aircraft, the secondary bays house heat seeking aim-9 sidewinders. We can envision the B-21 making use of secondary weapons bays to house self-protection air-to-air missiles like sidewinders or even aim 120 AMRAMs. Given the fact the Raider is an all-new aircraft, it could also make use of the AIM-260 Joint Advanced Tactical Missile or JATM. Since we haven't seen the Raider with open bay doors yet, it is possible that these secondary bays could be right next to the main weapons bay. But until we see more, we just don't know.
Speaker 1:
What we do know so far is that the B-21 is keeping its lighter color as compared to the B-2 Spirit. One of the first things that we noticed during last year's reveal is that the Raider appears to be coated in a light gray or white coating. Where older stealth aircraft like the Nighthawk and Spirit are coated in a much darker gray, the Raider's light gray coating seems to indicate that the aircraft could be able to operate in day or night conditions. Another interesting feature of the B-21 although this is common to flying wings is how much smaller it looks from the side. While flying wings are wide to produce the necessary lift, they are not as long as conventional aircraft. You can see this when we view our 3D model of the Raider next to a B-52. This shorter length undoubtedly plays a role in reducing the RCF to the aircraft from all angles.
Speaker 1:
As we learn more about the 6th generation Raider, I'll continue to make updated videos with updated 3D models. Much has happened since last year's reveal and, if you're anything like me, you can't wait to find out more. What do you think? Is the Raider the most advanced aircraft flying in the air today? What would the RCS be like when it's all said and done? Let me know in the comments below.
