Elon Musk says SpaceX is still building a third drone ship – but is it for Falcon or Starship?
Unprovoked on October 9th, SpaceX CEO Elon Musk tweeted “A Shortfall of Gravitas” – the name of a third drone ship settled on a year and a half ago – and reaffirmed that plans were still afoot to build a third rocket recovery vessel.
This is the first update on SpaceX’s newest drone ship in more than a year and comes just a few months after drone ship Just Read The Instructions (JRTI) – formerly stationed in California – was sent East through the Panama Canal. News that A Shortfall of Gravitas (ASOG) is still in the works raises the questions: what’s the holdup and what role(s) will the new drone ship play in SpaceX’s rocket recovery fleet?
Back in July 2018 and just shy of half a year after ASOG’s development was revealed, CEO Elon Musk indicated that the drone ship could be completed and ready for recovery operations as early as “next summer”, or Q3 2019. Now two weeks into Q4 2019, this can be interpreted in several ways, with the most likely explanation being that SpaceX’s naval contractor of choice is running behind schedule while building the new drone ship.
That’s the simplest explanation and operates under the assumption that Musk’s February 2018 comments remain true, meaning that ASOG is first and foremost (if not entirely) meant to support dual side booster landings for future Falcon Heavy launches and an increased Falcon 9 flight rate. However, recent developments give reason to believe that this may no longer be the guiding motivation behind SpaceX’s construction of a new drone ship.
Most notably, over the last several months of 2019, it has become increasingly clear that SpaceX plans (or hopes) to shut down its West Coast Vandenberg Air Force Base (VAFB) launch facilities for anywhere from 9 to 18 months. In just the last few days, word broke that Cape Canaveral Air Force Station (CCAFS) believes that it will be able to open an East Coast polar launch corridor (essentially the same thing VAFB offers) just months from now, and SpaceX hopes to be its first user as soon as February 2020.
Possibly along those lines, SpaceX took the step of sending West Coast drone ship JRTI on a several-week journey across the Panama Canal. The drone ship has since stopped in Louisiana for what is assumed to be maintenance and it remains unclear if JRTI will head to Port of Brownsville (Texas) to support Starship test flights or to Port Canaveral to fill the role ASOG was initially meant to.
As such, it’s no longer clear if SpaceX actually has a need for ASOG, at least as it was described last year. If SpaceX is moving JRTI east for the indefinite future, OCISLY and JRTI could easily support the Falcon 9 launch rates needed for Starlink and dual Falcon Heavy side booster recoveries, although Falcon Heavy is not scheduled to fly again until late-2020.
This leaves one obvious option left to explain ASOG’s continued existence and delayed debut: SpaceX may have paused work for a variety of reasons and changed ASOG’s design to account for a new role in the recovery fleet. That new role would likely center around the extremely rapid progress SpaceX is making with Starship as it pursues a series of ambitious flight tests that could begin before the end of 2019.
Of note, an August 2019 Draft Environmental Assessment (EA) of East Coast Starship launches revealed that SpaceX’s initially plans to land all Super Heavy boosters on a drone ship stationed a few miles off the Florida coast. Starship may also require drone ship landings in the early stages, at least until SpaceX is able to complete the environmental review and licensing process needed before it can begin to land Starship/Super Heavy at Pad 39A and Landing Zones 1 and 2.
For now, we’ll have to wait and see where drone ship JRTI heads after its Louisiana interlude and hopefully find out soon whether ASOG is a drone ship copy or something else entirely.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
