In December, Resilience Media received a press release announcing the UK’s first defence tech unicorn. The months-long investigation that followed is detailed in our article The Mystery of the British Unicorn, the story of our dealings with Roark Aerospace, the Unicorn we couldn’t find. This piece is available to our paid subscribers.

Resilience Media now offers extra, in-depth content designed for people building and investing in defence and security. Paying subscribers will receive access to premium content, early discounted tickets for Resilience Conference events, and invitations to exclusive, closed-door sessions at our conferences.

We’re offering an introductory rate of £80/year for the next three months, after which the annual price will increase to £120/year. This supports independent journalism by experienced writers in a world of increasingly AI-generated content and click-bait. We value your support for our work in this way.

Many of you pledged support for Resilience Media when we first launched. We really appreciate that early trust in our work, and want to thank you, our early subscribers, and the many people who have signed up for a paid subscription in the last 48 hours.

In the Deals section below, we dive into Rivan’s recent investment led by IQ Capital, as well as the Kraken-Anduril partnership. In the latest Dispatch from Ukraine, contributor Luke Smith sits down with Roman Sulzhyk from Resist.UA. Tiberius Aerospace said that it has completed the first successful demonstration of a new projectile that can be launched from standard howitzers but perform on part with more costly missile systems, which Editor-at-Large John Biggs reports on in our Startup Watch section.

Our next event is Resilience Conference Copenhagen, on May 11. We are thrilled to announce participation from EIFO, Systematic, Arctic Research and Development, D3, Lakestar, and more. They are leaders in defence investment, and in support for Ukraine, which is a story we will explore at the conference. Get your ticket today.

We pay for our events through tickets and sponsorship. We don’t have paid content, and we don’t take government money. This allows us to remain independent and curate challenging and impactful content. You can support our work by sponsoring our events. To discuss this, please contact me.

We’ve published all of the videos from Resilience Conference Warsaw, which you can watch here. Elsewhere on Resilience Media:

Rivan raises €28.7M to increase synthetic fuel production in Europe

  • UK-based startup Rivan has raised €28.7 million to expand domestic synthetic fuel production across Europe.
  • The round was led by IQ Capital with participation from Plural. It follows a €11.4 million seed round closed roughly ten months earlier.
  • The new funding will support deployment and manufacturing scale. First, they will build out Project Starwell, a plant in Wiltshire, England. It will be the “largest SNG plant in Europe and the first time SNG has ever been injected into the UK gas grid,” according to CEO Harvey Hodd.

Anduril taps UK’s Kraken to fast-track small USVs into US Navy hybrid fleet push

  • Announced at Sea-Air-Space in Washington, the partnership centres on developing and delivering small, fast, “quick-reaction” USVs aimed at both US and allied requirements.
  • The companies say Kraken’s K5 KRAKEN and K7 SABRE platforms will be manufactured and integrated under licence in the United States, paired with modular payloads intended to slot into a wider ecosystem of autonomous systems.
  • Instead of spending years designing something new, the pair is working with existing boats and wiring them into a broader mission system so they can slot into US and NATO operations.

Tiberius says it’s successfully tested Sceptre munitions that behave like more costly missiles

John Biggs, Editor at Large

One of the big themes running through recent conflicts in Ukraine and the Middle East has been how older, expensive “exquisite” weapons are being counteracted by a wave of new defence tech that is faster, cheaper and more advanced with autonomy and other capabilities. Today comes the latest instalment in that story, one that helps NATO-allied forces — already heavy with legacy equipment — update in a more cost-effective way.

Tiberius Aerospace said that it has completed the first successful demonstration of a new projectile that can be launched from standard howitzers but perform on part with more costly missile systems.

Tiberius — a UK and US startup — said that the projectile was launched as part of the tests it’s carrying out of its flagship Sceptre liquid munitions. The “liquid-fuelled ramjet projectile” gets launched from a 155mm howitzer but works like a precision-guided munition.

Tiberius said that the testing that was recently completed in New Mexico, in the US, saw the projectiles reach ranges of up to 150 kilometres. (This is roughly the distance, for example, between London and Calais, or between the Ukraine border and Kursk or Belgorod in Russia.) The plan is to continue testing to increase the range further.

The projectiles are capable of travelling at speeds of around Mach 3.5 and going up to altitudes of 65,000 feet, making the projectiles capable of bypassing common jamming and other electronic warfare interference. The projectiles can support payloads of up to 5.2 kilograms and they have demonstrated circular error probability of less than 5 metres, the company added.

Most importantly, the munitions can be manufactured in existing factories, reducing the capital expenditure and operating costs needed to get into production.

How to find the needle in the startup haystack in Ukraine: observations from an early-stage VC

Luke Smith, Contributor

After an investor demo day in early 2022, Roman Sulzhyk, head of investment at early-stage venture capital firm Resist.UA, found himself staring at a vat of solid rocket fuel brewing in a garage in a Kyiv suburb.

The tech was impressive, and so was the team — a handful of programmers and chemists, one of whom had been, in her own words, “about to go work at McDonald’s” before getting picked up by the startup.

These brilliant “kids” (as Sulzhyk calls them) had discovered that reducing the size of certain chemical components from 50 nanometers to 30 made the fuel polymerise far more efficiently.

“If we agree on the valuation,” Sulzhyk told the team, “you’ll have the money in your account within the week. We’ll shake hands today, and deal with the paperwork later.”

According to Sulzhyk, Western funds in Ukraine exist within a spectrum of risk tolerance, ranging from “crazy” risk tolerant to risk neutral. The most successful founders pitching to these Western investors typically are those who already have a track record. They not only know how to build a pitch deck and how to work with investors; they have built startups before.

But, as Sulzhyk told Resilience Media in an interview this month in Kyiv, in defence tech in Ukraine, there’s a “huge layer” underneath that one, a strata of first-time founders who might want to work with investors and could benefit from the contact beyond funding, but they don’t know how.

The experience that these founders come to the process with is limited, to say the least. They may not know what a minority investor is. They may not even speak English, which makes working with international partners a challenge.

Sulzhyk sees his role as making investors and the innovators readable to each other.

“I’m getting to those guys through word of mouth,” he said. They’re really excited, he adds. “They say, ‘Roman from Resist is very easy — you can talk to him, he can help you get to the next stage.’ That’s where we’re able to penetrate, where maybe others can’t.”
