Two new drone designs, Apollo and Athena, are in development at Kratos with a particular focus on collaborative operations with other crewed and uncrewed aircraft, and an eye toward sales in Europe. The modular Apollo and Athena designs are smaller than the company's XQ-58 Valkyrie, and could be configured to carry weapons, electronic warfare systems, or additional sensors.
Steve Fendley, President of Kratos' Unmanned Systems Division, shared details about Apollo and Athena in an interview with TWZ's Howard Altman on the sidelines of the annual Modern Day Marine exposition last week. In December 2024, Kratos confirmed to us that it secured contracts for both drones, but said it could not provide any additional information. During a quarterly earnings call in August 2024, Kratos CEO Eric DeMarco had disclosed the Apollo contract and said one for Athena was expected in the coming months. The company has yet to release imagery of either design.
'I can't say too much, but there they are high-subsonic systems,' Fendley told TWZ. 'They're quite a bit smaller than the [XQ-58] Valkyrie. So, much smaller footprint.'
Fendley also said that Kratos was targeting a sub-$5 million unit price for both Apollo and Athena, which have highly modular designs to allow them to be configured for multiple mission sets.
Per Kratos' website at the time of writing, the company says the Valkyrie is 30 feet long, has a 27-foot wingspan, a dry weight of 2,500 pounds, and a maximum takeoff weight of 6,000 pounds. The drone also has a stated cruising speed of 0.72 Mach, a maximum speed of 0.85 Mach, and a maximum range of 3,000 nautical miles. In 2022, the company also announced it had developed a Block 2 version with a heavier overall weight, but did not provide a specific weight figure. A number of additional variants have been developed since then, but specific details about their configurations remain limited.
Kratos has also said in the past that its goal is to eventually drive down Valkyrie's unit cost to around $2 million. However, last year, the company told TWZ that the price tag for a single XQ-58 was still between $4 and $6 million, depending on the exact configuration. In general, Kratos has historically focused on lower-cost designs and ones that can be manufactured relatively quickly.
Apollo and Athena 'are designed to be hard to detect,' Fendley added, but did not elaborate on. There are various ways to reduce an aircraft's radar cross-section, as well as its infrared, auditory, and visual signatures. For instance, the external moldline, the shape and position of the engine intake and exhaust, and other features of the XQ-58 contribute to that design's low-observability (stealthiness).
'The big focus' with both of the new drones 'is interactive collaboration of multiple aircraft at the same time,' Fendley explained. 'So multiple uncrewed aircraft at the same time, collaborating, [and] performing' missions with, 'basically, any fighter or attack aircraft in the inventory, that's that's the intent.'
'So joining those [Apollo and Athena] aircraft, or even Valkyrie, up with a fifth-gen[eration stealth] fighter, you have some capability to get to go out in front. You have some capability to basically light up the enemy,' he continued. 'But what's really interesting, when you combine it with a [non-stealthy] fourth-gen or even a third-gen system – which, of course, the U.S. doesn't do much of that anymore, but the international customers do – what you really do is you substantially increase the capability of that third or fourth-gen system because now it has off-board capability that's not adding risk to that system.'
'So let's pick an F-16. The F-16 can have a Valkyrie or an Athena or Apollo doing part of a mission that it normally would do, but it would have to be within a risk area to be able to conduct that part,' he added.
Speaking in more general terms about drones with the kinds of capabilities that Athena and Apollo are expected to offer, 'one use case is a system that's hard to detect … can, from a, let's say, from an EW [electronic warfare] perspective, can detect potential threats or potential targets of interest without being detected itself, which again, brings a capability that you can't do with a third or fourth-gen fighter system,' Fendley said. 'The other use case is if you have a group of them [the drones] and a handful of them are configured for EW, and a handful of them are carrying actual weapons – either air-to-surface, air-to-ground, or air-to-air – the sensor system can identify the target, can point out the target, basically pass the coordinates, and then the weapons aircraft can conduct the termination mission.'
'One of the other things that allows us to be more cost-effective than others is we don't put all that on one aircraft,' he continued. 'Let's just talk in rough numbers. Let's say there are six useful mission systems. And, again, rough numbers. Let's call three of them sensor-type systems, three of them weapon-type systems. We won't put all six on any one aircraft. We'll distribute that. It allows each aircraft to be much less expensive. It also allows you in a large mission, it allows you to distribute your risk and make it very hard for the enemy to decide 'do I want to shoot down a sensor airplane or a weapons airplane?''
For years now, TWZ has been highlighting the inherent benefits of distributing systems and associated roles among individual drones in a fully networked swarm or other collaborative environment. Beyond helping to reduce the cost of each uncrewed aircraft, including just by allowing them to be smaller and less complex, this also offers valuable operational flexibility since different drones can be performing multiple tasks simultaneously. It also means that the loss of some number of drones is less likely to immediately render the entire group ineffective.
That stealthy 'loyal wingman' drones that also feature high degrees of autonomy and collaborative capabilities could be especially valuable force multipliers when paired with fourth-generation crewed combat jets is something TWZ has noted in the past, as well. This was a particular key point in a detailed case we previously laid out for how the trilateral Australia-United Kingdom-United States (AUKUS) defense cooperation agreement could offer an ideal framework for the shared development of loyal wingmen-type drones.
In speaking with TWZ, Fendley also talked about out how the modularity of the Apollo and Athena drones could allow them to be better tailored to a customer's particular needs from a regional perspective.
'The European market is very different than the Pacific markets. The European market is more interested in, let's call it, … sensor capability, weapons capability doesn't need the long legs, the long endurance that you do for the Pacific,' he explained. 'What that allows you to do is that allows you to really load that airplane up with more weapons, for example, than you would for an aircraft that's going to the Pacific, but has to fly a long way, so it's carrying fuel. So that's kind of the trade there.'
Right now, Kratos is working on Apollo and Athena configurations 'to focus more on that European market,' he added.
There is already extensive work ongoing on various tiers of drone 'wingmen' across Europe, including in the United Kingdom, France, Germany, Poland, and Turkey. This reflects a global trend, as well. However, if Kratos can offer a particularly low-cost option that is readily adaptable to multiple mission sets, it could be very attractive to smaller air forces looking to bolster their airpower capabilities and overall capacity, and that cannot afford more exquisite crewed or uncrewed platforms.
The core attributes of Apollo and Athena could be of interest to larger air arms, as well. The U.S. Air Force has indicated that it may now be leaning toward cheaper and simpler designs for the second iterative development phase, or Increment 2, of its Collaborative Combat Aircraft (CCA) program. Kratos, which was notably absent from the CCA program's Increment 1 competition, has said on several occasions that it is interested in taking part in Increment 2. General Atomics and Anduril are currently developing designs, now designated YFQ-42A and YFQ-44A, respectively, under Increment 1. The Air Force has also previously said that Increment 2 could be the first phase of the CCA program to weave in foreign participation.
The U.S. Marine Corps has separately said it is looking into whether certain roles and missions that are typically associated with larger, more exquisite drones, could be performed, at least in part, by smaller designs. It's worth noting here that the Air Force and the Marine Corps are also currently the only two known operators of Kratos' XQ-58.
The U.S. Navy has also outlined a vision for future carrier-capable CCA-type drones that would be low-cost enough to be 'consumable,' and then expended as one-way attack munitions, or as targets in training or testing, at the end of relatively short service lives. CCA-related work across the Air Force, Marine Corps, and Navy is directly intertwined via a joint service agreement.
With Kratos now having secured contracts for both Apollo and Athena, more details about both of these specific designs may begin to emerge.
