US Air Force issues RFP for massive rockets, SpaceX’s BFR could be one of them

Published

The US Air Force has released a Request For Proposal (RFP) that hopes to fund the development of multiple heavy-lift rocket prototypes to launch no later than 2021. The USAF specified on October 5 that it wants to partially fund prototype development for at least three promising US-sourced launch vehicles, while maintaining the options to select none of the proposals or even more than three. The purpose of these broad strokes is to provide the Air Force and US military in general redundant access to space by way of “at least two domestic…launch service providers” capable of meeting National Security Space (NSS) requirements.

However unlikely it may seem, NASA experienced this firsthand when two of the vehicles it funded, SpaceX’s Falcon 9 and Orbital-ATK’s Antares, experienced complete failures within less than a year of each other. Both vehicle failures destroyed supplies intended for the International Space Station and forced NASA to rely on Soyuz missions to fill the gaps created while producing considerable uncertainty for the agency. By funding two or more independent launch vehicles, the Air Force would lessen the impact of such failures, and this assured access is rightly perceived as an invaluable commodity in the military.

Several details in the latest proposal make it relatively easy to name the obvious prospective applicants. The payload requirements necessitate heavy lift or even super-heavy lift launch vehicles capable of placing anywhere from 5,000 to 37,500 pounds into a variety of Earth orbits, ranging from low Earth orbit (~500 mi) to direct transfer geostationary orbits (~19,200 mi). This narrows the field considerably, pushing out all smaller-scale vehicles. Also telling is a requirement that proposed launch vehicles make use of rocket propulsion systems (RPS) already funded for development by the USAF if at all possible.

Considering the inherently complex and difficult process of developing massive rockets, initial launch dates no later than 2021 (or 2024) likely mean that the vehicles being considered must already be under some level of serious development. This leaves us with four possible options in the US, undoubtedly not a coincidence given the RFP’s explicit goal of facilitating the creation of “at least three…prototypes as early as possible” and “at least two domestic…launch service providers”. These four vehicles are SpaceX’s BFR, Blue Origin’s New Glenn, ULA’s Vulcan, and Orbital-ATK’s NGL, all of which already have tentative inaugural launch dates clustered from 2019 to 2022. Perhaps even more revealing, all four vehicles can be expected to utilize several rocket propulsion systems (rocket engines) already funded by the Air Force, namely SpaceX’s Raptor, Blue Origin’s BE-4 and BE-3U, and Aerojet-Rocketdyne’s AR-1.

While the development of BE-4 and AR-1 have been somewhat veiled, SpaceX’s Raptor engine has publicly made a great deal of progress. As discussed during Elon Musk’s IAC 2017 presentation, the company has conducted an array of successful tests with its subscale Raptor program, to the tune of 42 individual hot-fire tests totaling more than 1,200 seconds. Musk also reported that the only thing preventing tests longer than 100 seconds was the size of the propellant tanks at the test stand, a genuinely impressive accomplishment if true. The sticking point, however, is how much difficulty SpaceX will have as they transfer to full-scale Raptor testing. The subscale Raptors being tested have a reported thrust of 1,000 kN, whereas the new full-scale thrust targets for BFR have settled on 1,700-1,900 kN, considerably smaller than the 3,000 kN figure from 2016 but still nearly a factor of two larger than the test articles SpaceX has had success with. In fact, educated speculation from SpaceX fans suggest that the operational Raptor as shown in 2017 may only need to be about 15% larger than the current test article(s). The pressure the full-size engine operates at will be considerably higher, so SpaceX’s work is not done by any means, but the company’s next-gen rocket propulsion system is arguably far closer to completion than any of its competitors’ offerings.

As far as we are publicly aware, SpaceX’s subscale Raptor testing has yet to result in a major failure and has largely been a great success. Blue Origin’s BE-4 is known to have experienced at least one critical failure during hot-fire testing, while AR-1 has not yet begun full engine tests but is well into concrete hardware testing. Blue Origin’ s BE-4 engine and its New Glenn rocket are currently expected to fly for the first time before 2020, with AR’s NGL tentatively planning for a 2021 inaugural flight, assuming the company chooses to continue pursuing its development.

SpaceX has not yet specified when BFR or BFS will first take flight. Raptor is likely to begin full-scale testing relatively soon, and Musk revealed that SpaceX was aiming to begin construction of the first BFR as early as Q2 of 2018. It’s quickly starting to look like the U.S. is about to enter a sort of modern commercial space race and regardless of the outcome, the next several months and years are bound to be tense and exciting for SpaceX, Blue Origin, and the established incumbents as they battle for both public and private contracts.

Tesla Model Y reclaims elusive sales title in competitive market

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

The Tesla Model Y reclaimed an elusive sales title in one of the most competitive markets it is in, outpacing key rivals and formidable competitors to regain the crown it once was a shoe-in for.

As more EVs have entered the market and some at better prices, Tesla’s Model Y has been put up against some very attractive options.

This is especially prudent in Europe and China, where domestic car companies have been offering attractive and cheap EVs as Tesla alternatives.

However, in September, the Model Y was able to battle back and take over the top sales spot for EVs in Europe.

In September, it had 25,938 sales, and although it was an 8.6 percent decrease compared to the same month in 2024, it was enough to be labeled the best-selling car in the European market, Automotive News reported.

500-mile test proves why Tesla Model Y still humiliates rivals in Europe

There are four vehicles that have been atop the European EV sales rankings for any given month this year: the Renault Clio, which has three titles, the Dacia Sandero, which has won four monthly sales titles, and the Volkswagen T-Roc, which was the best-selling car in the market in August.

The Clio captured the number-two spot in September with 20,146 sales.

Despite a strong September showing for the Model Y, which was its first monthly sales crown of the year, the vehicle has not been a top-three EV in Europe this year. That is still led by the Sandero, Clio, and T-Roc.

Despite that, Tesla’s Model Y is still likely to be one of the best-selling vehicles in the world, if not the best, for the year.

In the United States, it has dominated EV sales charts and has been one of the most popular cars in the region. The same goes for China, where the Model Y has more competition than in Europe, but is so attractive because of its premium look and feel, as well as its tech offerings.

The Model Y has been the best-selling car globally for the past two years, outpacing widely popular gas and EV models from around the world.

Tesla also just finished up its best three-month sales period in its history, delivering just shy of half a million vehicles from July to September.

A Tesla captured video of a crashing plane on an Oklahoma highway, as a shocking video shows a small aircraft coming across a local roadway, with various cars ducking to avoid it.

On October 23, an Oklahoma National Guard OA-1K Skyraider II turboprop plane crashed during a training mission after an engine failure. Both crew members escaped unharmed, but they were not the only ones at risk of injury.

A Tesla Dashcam video shared by a friend of the car’s owner shows the vehicle narrowly avoiding an impact with the plane, swerving left, then back onto its side of the road. It appears to be a serious miracle:

David Bellow, the person who posted the video of the Tesla avoiding the plane, claims it was Full Self-Driving that performed the maneuver, but it is not confirmed. This is what he said:

There are a few hints that suggest it could be Tesla’s Full Self-Driving suite, but it is important to note that neither the company, the driver, nor the friend has confirmed this.

The first hint is the vehicle’s maneuver and subsequent reaction. The car suddenly swerves to the left, which any human would do, but how the vehicle continues to travel as if nothing had happened seems to solidify the idea that FSD could have been involved in avoiding the plane.

Nevertheless, this does not confirm that FSD was in control.

My Tesla did this on FSD (Supervised) v14.1 and the internet went crazy

Most people would likely have stopped in their tracks after avoiding an aircraft while driving.

However, this is not enough proof to definitively say FSD was responsible for the avoidance.

Additionally, the “Jump to Event” button is activated in the video, suggesting that FSD was in control. The vehicle gives this option when something major has occurred, including human intervention.

Regardless of whether the car was on FSD or was controlled manually, it is pretty crazy to have this piece of dashcam footage.

Tesla Full Self-Driving got a minor feature that’s a massive improvement

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.”

Tesla’s Full Self-Driving suite seems to get better with every single release. However, it is also making it more seamless and easier than ever to use for passenger travel, thanks to a recent feature that has flown under the radar.

Tesla started rolling out its v14 iteration of the Full Self-Driving suite a few weeks ago to Early Access Program (EAP) members, and it finally started making its way to the public for the first time earlier this week.

Tesla Full Self-Driving v14.1 first impressions: Robotaxi-like features arrive

The wide rollout of Tesla v14.1.3 was long-awaited, as its capabilities were flexed by the handful of people lucky to have it. However, those sitting with v13.2.9 were still eager to get to their hands on the new FSD version, especially considering it came with a lot of cool upgrades.

One of which is flying under the radar and not getting as much attention as it should. Although it is a minor feature change from v13, Tesla has made FSD more seamless than ever with a simple fix that it started utilizing with v14.

With v14.1.1, Tesla started rolling out the removal of the “Brake Confirm” feature, which required drivers to touch the brake to activate Full Self-Driving. This is now an optional feature, as it now is defaulted to the off position by the car.

The release notes for the feature state:

“Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.

You can enable Brake Confirm in Autopilot > Brake Confirm.”

Simply put, you no longer need to touch the brake to confirm your intention to use Full Self-Driving, which is a small but very effective fix.

It makes your car much more active in terms of overall activation, and it is definitely a quicker and more streamlined departure from your current location than ever before.

Here’s a good look at how quick it is:

@teslarati With Tesla Full Self-Driving v14, there is no delay when you start FSD. Press “Start Self-Driving” and you’re on your way #fyp #viral #tesla #teslafsd #fsdv14 ♬ original sound – TESLARATI

The feature is small, but it is very noticeable with your first uses of FSD v14. Eventually, it will become even more streamlined as Tesla solves self-driving and autonomy, as it will require zero human intervention to get started, which means the “Start Self-Driving” button will also be removed.
