  1. This is the final craft installment for Jet of the Day, it's been a wild ride! 2018 - Boeing KC-46 Pegasus The KC-46 is a next-generation aerial refueling and cargo aircraft developed as part of the KC-X program in 2006. Boeing adapted their 767 passenger/cargo aircraft to the roles required in the KC-X competition. The Pegasus can be used in a variety of roles, including cargo, aerial refueling, and as a flying hospital. The Pegasus contains equipment for both boom and probe and basket refueling. It's late, and the Pegasus is pretty self-explanatory, so have some more pictures of this beast of a plane. You can see the two extra refueling pods on the end of each wing. They allow the KC-46 to refuel up to three aircraft at the same time. I've attempted refueling my F-22 with the KC-46. The refueling drogue seems to be easier to use than the typical boom design, as you can fly into the port instead of up onto it. That said, it's not easy either way. Replica Statistics: Builder: Servo Part Count: 340 Mass: 79.5 tons Crew: 3 Top Speed: 240m/s Service Ceiling: 8km Powerplant: 12x Wheesley Dimensions: 34.75 x 32.6 x 12.52 This KC-46 is the final craft in the Jet of the Day Series, so I put a lot of time into making it look as accurate as possible. It features a unique nose design, built completely out of solar panels. Additionally, it has an accurate set of flaps and spoilers, plus a combination of crew and refueling capabilities. However, the most interesting part of this craft is (what I believe to be) the first-ever stock probe-and-basket refueling system in KSP. How to use it: 1.) Make sure you have ignore crash damage enabled. I think it will work without it, but there’s a solid chance it just explodes. 2.) Use action group 1 to decouple the boom. The boom should self-deploy. If it doesn’t immediately re-dock, pitch up and down to make the docking ports stick. Use action group 2 to toggle the boom engines off. 3.) Use action group 1 again, then switch to the boom and throttle up to full. Again, it should move forward by itself Download Link: In the Future: @NorthAmericanAviation and I are working on a short recap video for the series, that will be out sometime in the next week. Expect updates, plus discussion on where the series/concept is going from here. It's been awesome working with NAA, so I doubt that this thread is the last that you've seen of us. To the readers: What do you want to see in the future? More builders? Russian Jets? Space missions? Experiemental craft? All of the above! We'd love to hear what you guys thought of the series and what we should do in the future
  2. Yes it is! This is actually one of the first craft that I made for JotD, so I guess it's fitting that it's the penultimate edition. July 2015 - Lockheed Martin F-35B Lightning II (Joint Strike Fighter) The F-35 is a family of three fifth-generation stealth fighters being produced by a number of companies, including Lockheed Martin, Northrop Grumman, BAE systems, and Pratt & Whitney. The F-35 family consists of the F-35A, a conventional takeoff and landing fighter produced for the U.S. Army; the F-35B, a S/VTOL fighter produced for the U.S. Marine Corps; and the F-35C, a carrier-adapted version for the U.S. Navy. Additionally, a number of western nations have bought into the F-35 program to replace other aging fighters, including the 40-year old F-15 and F-16s. The F-35A is designed to replace the F-15 in the air superiority role, and the F-15E in the ground attack theater. In order to achieve these goals, the F-35A is equipped with advanced battlefield integration. This allows the pilot to share information with ground forces or other aircraft in real time. The main role that the F-35 is not designed to take over is the dogfighting role. In the words of Air Combat Command head Mike Hostage, "any F-35 pilot that enters a dogfight has made a mistake." Additionally, the F-35A is the main export version of the F-35. Export versions have several minor modifications, depending on the importer. Japanese F-35s have both rigid boom and probe and basket refueling systems, and Norwegian F-35s have a drogue chute pod. The Royal Netherlands Air Force and Royal Australian Air Force, in addition to the Turkish, Israeli, and Singaporean air forces will all be operating F-35As in the next five years. The VTOL capabilities of the F-35B, unique among active fighters (the Harrier is an attack aircraft), are thanks to the unique engine layout. All F-35s are powered by the Pratt & Whitney F135 engine, the second afterburning stealth engine (the first powered the F-22 Raptor). The F-35B uses a modified F135 as well as a Rolls Royce LiftSystem, the vertical lift fan that balances the F-35B. Additionally, there are small underwing jets that allow roll control while hovering. The VTOL capabilities will allow the Marines to use the F-35B in similar roles as the AV-8B Harrier II, while also providing a supersonic fighter and air superiority aircraft. The Marine Corps, in addition to the Royal Air Force and the Italian Air Force will be equipped with F-35Bs in the future. The F-35C was created for the U.S. Navy, and features a number of modifications to make the aircraft more suitable for carrier operations. It features increased tail and wing area to lower approach speeds, folding wings, and has strengthened landing gear and mainframe, and a tailhook for carrier landings. The U.S. Navy will be the sole customer for the F-35C. Replica Statistics - F-35B Builder: Servo Part Count: 146 Mass: 15.6 tons Crew: 1 Top Speed: 260m/s Service Ceiling: 8km Powerplant: 2x Panther (horizontal) + 2x Panther (lift fan) Dimensions: 12.14 x 8.56 x 4.09 LWH This F-35B will probably remain one of my favorite craft for a while. The engine transition is so smooth, and it looks awesome doing it. Unfortunately, the flight performance is mediocre overall, but it's an awesome craft nonetheless.

  3. (Yesterday) I spent some time flying my YF-23 and F-22 around. Using my dogfighting technique, I determined that the YF-23 sucks at dogfighting, but is faster (exactly like the real thing) than the F-22 in non-afterburning flight. I also spent a bit of time attempting to refuel my F-22 in midair using my KC-46. It went just as well as my other aerial refueling attempts did (which is to say, close, but no cigar.) It did prove that my probe-and-drogue system is working, which is exciting.
  4. You and me both... The F-22 is an attractive craft, but the F-23 is on a whole new plane. And with that awful pun, on to the F-22! December 2005 - Lockheed Martin F-22 Raptor The F-22 Raptor was the ultimate winner of the ATF competition against the Northrop YF-23. It was a more capable dogfigher, putting it a step ahead of the -23 in the USAF’s mind. The first F-22s entered service in 2005, and through 2012, almost 200 examples were built. F-22s have extremely effective all-aspect stealth, allowing them to engage and destroy threats before even appearing on the enemy radar screens. In one famous example, a F-22 intercepted a pair of Iranian F-4s and flew under them without being detected at all. Only when the F-22 radioed to the F-4s did they realize that they had been intercepted. Replica Statistics Builder: Servo Part Count: 121 Mass: 18.6 tons Crew: 1 Top speed: 550m/s Service Ceiling: 10km Powerplant: 2x Panther Dimensions: 14.57 x 9.58 x 3.97 LWH I’m really proud about this replication, particularly the engines. In my opinion, it nails the tradespace of appearance - part count - performance. I feel like I did a good job rendering the Raptor - particularly the engines - in a comparatively low part count. Additionally, this F-22 performs extremely well. If you unlock the second tail vane, it is a very maneuverable dogfighter. Additionally, it has can almost supercruise without afterburner, and with burners lit it can reach mach 2 at altitude. Thanks to the large number of wing parts, it also glides at about 45m/s. In all, it’s an extremely fun craft that I’m sure you will enjoy as much as I did. Download Link: Tomorrow's Craft: Lockheed Martin F-35 Joint Strike Fighter Lightning II
  5. Edited to fix, thanks for the heads-up. The Advanced Tactical Fighter competition was initialized in 1986, with Lockheed Martin and Northrop being selected to build aircraft. The YF-22 was selected in 1991, and developed into the F-22 over the next ten years. The Raptor entered service in 2005. Production continued until 2012, when plants began tooling up for the F-35. There have been talks of reviving the YF-23, particularly the Next-Generation Bomber competition. The design competed against a modified Raptor, as well as a next-generation flying wing from Boring. The competition was cancelled before any aircraft were built.
  6. That's one of the possible ideas, along with Russian jets. Either way, I think it would have to be a whole lot more than two of us building and publishing the craft. We do have a surprise planned for the end of JotD, though. More on that after we decide what that surprise is. Also, I'm bumping the F-22 to tomorrow, because today's craft technically came first. Also came before the B-2, but I'm grouping it with the F-22. June 1991 - Northrop YF-23 ATF Demonstrators "Black Widow II" and "Gray Ghost" The YF-23 was Northrop’s submission to the USAF’s Advanced Tactical Fighter design competition, competing against the YF-22. Two YF-23s were built, under the monikers Black Widow II and Gray Ghost. In combat trials against the YF-22, the YF-23 proved to be faster and stealthier, although the USAF valued the agility of the YF-22 above all else.The AFT competition resulted in the first fifth-generation fighters to enter service. Fifth-generation fighters incorporated advanced stealth stemming from advanced computing techniques, supersonic cruise speeds, high maneuverability, and advanced connectivity with other aircraft and ground systems. The YF-23 is a new and striking design for fighters. The trapezoidal wing is unique in a field dominated by delta winged fighters. Additionally, the YF-22 has the ability to cruise at mach 1 without using afterburners, allowing for extreme range. Replica Statistics Builder: Servo Part Count: 85 Mass: 10.4 tons Crew: 1 Top Speed: 450m/s Service Ceiling: 10km Powerplant: 2x Panther Dimensions: 12.78 x 9.29 x 3.37 LWH This YF-23 is an updated version of the one I posted several months ago. I modified pretty much everything except the wings in this version, cleaning lines and making it mirror the actual YF-23 more accurately. This model can cruise for about 20 minutes without afterburner (only about 4 with afterburners). Outside of that, it handles pretty well from everywhere from approach speed to supersonic, and looks awesome doing it. Download Link: Tomorrow's Craft: Lockheed Martin F-22 Raptor
  7. I was using the octagonals to get an idea of the nose shape, and then once I built the solar panels around them, I removed the frame. It was extremely helpful for getting the shape down. The KC-46 is pretty much finished. I still have a few minor tweaks I want to make before I release it at the end of the week. It's got working flaps and spoilers (I couldn't get slats to look good, so I omitted them), plus the probe and drogue that is the main interest (IMO) of the design. Unfortunately, you have to turn on "no crash damage" to make it work, but that's the price to pay for a stock PnD system. In theory, this system is easier to use than a boom system (you can fly into it rather than up onto it), but it's still really hard. Also, it's harder to incorporate the docking port for PnD than for boom systems. I may wind up putting a boom on this; I'm not sure. There's space for it, but I really don't want to add that complexity to it. I also revamped my YF-23 (updated wing + engine housing + tail). Of the two, the F-22 is a much better dogfighter (both IRL and in KSP), which was the main reason the -22 got the contract instead of the -23. I still maintain that the YF-23 is a cooler airplane for what that's worth.
  8. Not sure I like the radiators on the front half. I may go 100% solar panels. After that, all I have to do is add a tailplane and landing gear and flight testing should be underway. This is the first plane that I've equipped with full on flaps+spoilers (I may do slats as well, because why not?), so hopefully they will serve their purpose. Also, another thought - I could replace the radiators around the cabin and aft section to go completely radiator-free. That should make everything a lot cleaner lines-wise.
  9. I began work on my KC-46's cockpit today. I'm using a variety of techniques new to me (and possibly some of you). The first was framing the cockpit in octagonals. At the cost of temporarily doubling the part count, I now have a really solid frame from which to work. Second, I've never seen people use shielded solar panels as a structural element. I may find a reason why, but for now, they are smaller, cleaner, and smoother than elevons + wing plates. It's not finished, but it's progress.
  10. I imagine that it could be done, given enough moving parts. If anyone could do it, it would be @EpicSpaceTroll139. And back on the train of doing stuff never before done in stock KSP (I think), I'm working on a probe and drogue refueling system for my KC-46. Basically, the tube has a bit that rolls from front to back docking in either position. There are jet engines to push it forward, and the drag from the fins should bring it back easily enough. Here's my fuselage work for the KC-46 so far.
  11. Welcome to the forums! Awesome craft + post, great work.
  12. Clip one of the parts up slightly from the other (it's possible to do it without. It's not a perfect fit, but it eliminates the z-fighting. I've used this on so many wings, and fuselages.
  13. Thanks for the compliment! As for the controls, you're right - I can never remember which controls control what function after I close KSP. I edited the OP + the KerbalX page. Glad that you're enjoying the craft
  14. I'm pretty impressed that I made it in so soon. From what I've seen, most people in this group have significantly more posts than rep. I guess that's because I'm not a prolific poster, and instead mainly post to screenshot-sharing threads rather than discussion threads. Either way, I'm honored to make it to 1k.
  15. How did you manage that bomb bay? It is hinged, or is there another trick? Speaking of F-22s, I took @EVA_Reentry's suggestion with the wing chords and nose. Here's a side-by-side comparrisson: Pretty subtle stuff. The sweep angle was increased slightly, wingspan was decreased slightly. The nose isn't any shorter, but it's flatter. This will probably be the release version for JotD, since I'm really happy with both the performance and the aesthetics of the design. It can hit mach 2 at altitude (mach 1.25 at sea level). Rate of climb and maneuverability are comparable to the real thing. The only capability it lacks (beyond weapons/weapons bays) is the supercruise without afterburners. It tops out at about 290m/s without the 'burners.
