SpaceX's Falcon rockets might need a giant tower on wheels for US military launches

SpaceX reportedly plans to build a massive mobile gantry – effectively a tower on wheels – at one of its two Florida launch pads, a bid to meet obscure military launch criteria needed to secure highly lucrative Falcon 9 and Falcon Heavy launch contracts from the US government.

Although this is not the first time that SpaceX and vertical integration have been thrown around in the same sentence, it is the first time that the company is reportedly close to actually finalizing its plans along those lines and constructing a real solution at one or more of its three orbital-class launch pads.

Throughout the entirety of its active launch operations, SpaceX has relied exclusively on horizontal integration for its Falcon 1, 9, and Heavy rockets and the satellites they launch. CEO Elon Musk and other executives have maintained a consistent rationale for that preference over the years: ensuring that rockets and payloads can be horizontally integrated is the best possible solution so long as SpaceX’s primary motivation is improving access to space and lowering the cost of launch. As such, SpaceX has one and only one major motivation to jerry-rig a vertical integration solution for its Falcon family of rockets: necessity by way of arcane US military launch contract requirements.

Spaceflight Now broke the latest news first on January 3rd, 2020, revealing that SpaceX was at long last taking a substantial step towards actually building its own vertical integration infrastructure at Kennedy Space Center (KSC) Launch Complex 39A – a step that was long anticipated but has taken years to transpire into anything concrete. The gist is this: for a variety of seemingly shoehorned and far-from-obvious reasons, the secretive, ultra-expensive spy satellites that contractors like Lockheed Martin and Boeing build for the US Air Force (USAF) and the National Reconnaissance Office (NRO) builds itself are designed in such a way that they apparently cannot be flipped horizontally in a rocket’s payload fairing.

Although taken from Blue Origin’s New Glenn payload user’s guide, SpaceX’s process of encapsulating satellites in Falcon payload fairings is functionally identical. (Blue Origin)

Identical to the process depicted above for Blue Origin’s in-development New Glenn rocket, up to now, SpaceX has encapsulated all satellite payloads vertically, sealed the payload fairing, rotated that integrated fairing and payload, and then attached that assembly to horizontal Falcon 9 and Falcon Heavy rockets. The rocket is then transported to the launch pad on a transporter erector (T/E), which – as the name suggests – raises the rocket and payload vertical before propellant loading and launch.

For certain USAF and NRO launch contracts, breakover (horizontal flip) is unacceptable and their preference is that the launch vehicle be brought vertical before the payload – also still vertical – is stacked on top. While it sounds simple in principle (i.e. “Just stick a crane out by the pad!”), vertical payload integration is exceptionally tedious unless you already have the infrastructure in place. Competitor United Launch Alliance (ULA), for example, already has that infrastructure – having held a decade-long monopoly over US military launches that only ended 5-7 years ago, depending on how it’s measured.

Both ULA’s Atlas V, Delta IV, and soon-to-be Vulcan Centaur rockets and the infrastructure used to launch them have all been designed around vertical payload integration – essentially requiring massive, expensive, and complicated buildings-on-wheels at each launch facility.

In effect, SpaceX must partially copy competitor United Launch Alliance (ULA) by building its own massive service tower to evenly compete with the company on the latest lucrative US Air Force launch contract.

Per Spaceflight Now, SpaceX has plans to build a similar mobile tower at Pad 39A, currently dedicated Falcon 9/Crew Dragon missions for NASA and the occasional Falcon Heavy launch. That tower will ultimately roll up to Falcon 9 or Heavy rockets on the pad, fully covering the vehicles and giving technicians an array of work platforms and tools to support vertical payload integration, among other uses. SFN says that the mobile tower will be even taller than the existing Fixed Service Structure (FSS) tower at Pad 39A, measuring some 30 stories (100m/330ft) tall.

In line with a recent FSS redesign that saw that existing tower modified for Crew Dragon and outfitted with semi-transparent black glass or plastic and a black-and-white color scheme, the new mobile tower will apparently be built with a similar design language.

While now outdated, SpaceX’s 2016 Mars rocket featured a giant crane used for vertical integration. BFR appears to use the same approach. (SpaceX)

Ultimately, all of SpaceX’s plans for Starship – a massive next-generation, fully-reusable rocket – have relied on some form of vertical integration for Super Heavy boosters, Starships, and tankers. In a best-case scenario, all of those vehicles may one day land in reach of a giant crane situated at the launch pad, allowing SpaceX to lift them back to the pad and install ships and tankers on Super Heavy boosters just hours (maybe even minutes) after touchdown – truly rapid reuse.

For now, it’s unclear when exactly SpaceX wants to start cutting metal for its new Falcon 9/Heavy gantry, but it’s safe to say the company will move fast as usual once it begins.

Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.

As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.

The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.

During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.

Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.

Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama

Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.

Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.

Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.

Ford said on X today that Ontario is banning American companies from provincial contracts:

“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”

It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.

Musk responded in simple terms, stating, “Oh well.”

It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.

As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.

It is also expanding to new territories across the globe on an almost daily basis.

With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.

The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
