--- Designed as a direct competitor to the Horus-Class Scout, the Set-Class boasts a quarter of the cross-section of it's counter-part. While the Horus-Class focuses on bringing large sensors a far distance for relatively little cross-section, the Set-Class focuses on bringing smaller sensors to bear more rapidly. The Set-Class is well, better set with regards to crew ergonomics. While the Horus-Class was roomy, almost to a fault, the Set-Class is more compact, but with a better layout. The Set-Class features a command station for a CO, with it's other four positions being well arrayed in the craft's admittedly roomy operating spaces. While leg room is at far more of a premium, and sleeping quarters are spartan, the work spaces fo a Set-Class Scout are not. This is due to the fact that the Set-Class was designed from the ground up with recon in mind. The Project Set engine was designed for high-output, while the ship's sensor suites are purpose built for the Set-Class and the Set-Class alone.
--- However, the Set-Class could not replace the Horus-Class for a few reasons, not the least of which was range. The Horus-Class boasted better range both for the craft itself as well as it's sensors package. The other reason was crew bias; simply put the Horus-Class was a desirable posting, with lavish quarters even compared to large ships and an excellent working space more akin to a Bridge than a cockpit, the Horus-Class was simply adored by her crew. Finally, the Horus-Class was much easier to maintain, leading flight crews to love it as well. The Set-Class was by no means a nightmare to work on, indeed it was quite easy to maintain, however the Ankh-Class would go on to develop a reputation for being particularly easy to work on, and thanks to having it's Engineering Space re-designed to better fit it, the Horus-Class became known as a mechanic's dream. These things kept the Set-Class from ultimately replacing the Horus-Class, however it's ability to be in more than one place at once for the same mass, plus it's speed ensured that the Set-Class had a place in the navies of the Principality for generations to come.
