The United Kingdom is set to acquire a new class of 13 Type 100 Merlin-class stealth cruisers under a programme intended to enhance survivability and operational flexibility in contested environments, according to industry sources.

The vessels, understood to be part of a previously undisclosed maritime capability initiative, will reportedly incorporate an advanced low-observability architecture designed to significantly reduce their detectability across multiple domains. Officials have suggested that the ships will be “extremely difficult to identify through conventional means,” with one source indicating that visual confirmation may be “challenging under most conditions”.

While detailed specifications remain limited, the design is expected to prioritise signature management to an unprecedented degree. This is believed to extend beyond radar cross-section reduction to include infrared, acoustic, and potentially even visual spectrum considerations. As a result, observers may find it difficult to clearly determine the ships’ outline, position, or, in some cases, whether they are present at all.

The Ministry of Defence has not publicly confirmed the programme, though multiple figures familiar with the effort describe it as a “step change” in how naval platforms are conceived. One individual suggested that the vessels could “operate in plain sight without being readily perceived,” adding that their presence may only be inferred indirectly.

Questions remain over how the fleet will be integrated into existing force structures. Analysts note that traditional methods of tracking and tasking units may require adaptation if the ships prove as difficult to detect as described. There is also uncertainty around basing arrangements, with some speculation that locating the vessels when alongside could present “unique practical considerations”. Industry representatives have indicated that the programme has progressed smoothly, with early production units already “delivered in principle”. However, efforts to verify their status have proven inconclusive. Requests to view the vessels or obtain imagery have, so far, not yielded definitive results.

In at least one case, a scheduled visit to a naval base reportedly included a briefing on the vessels, followed by a tour of an entirely empty berth. Attendees were assured the lead ship was present, though none could independently confirm this. One remarked that the programme appeared to have “achieved a level of discretion not previously thought possible”.

Defence analysts have begun to question whether the programme represents a genuine procurement effort or something more conceptual. One noted that a warship which cannot be seen, tracked, located, or verified in any way “does solve survivability concerns,” but conceded it also introduces “new challenges, such as confirming it exists.”

Despite this, officials remain confident. One source summarised the programme succinctly: “They are completely undetectable, entirely unobservable, and, for all practical purposes, indistinguishable from not being there at all.”

The UK Defence Journal understands that all 13 vessels are now in service. Their current locations, status, and indeed their existence remain unclear. A senior minister, speaking on background, welcomed the programme’s value for money and hinted at expansion: “These ships deliver exceptional capability at effectively no cost to the taxpayer. Because they cannot be seen, they also cannot be over budget. We are therefore actively exploring options to grow the fleet further.”


Congratulations, and thank you for reading the whole article; this is just an April Fools Day joke. The article above is not true, and if anyone is sharing it after April 1st, please remind them of that fact. The purpose of this article, aside from our usual April Fool’s Day joke, is to make the point that reading beyond the headline should be the norm every day, not just on the 1st of April. There’s a large volume of misinformation online. Make sure you don’t add to it by sharing articles without reading them. Finally, be careful of the person sharing this article after the 1st of April as they very clearly don’t read what they share.

  1. Yes I have the contract for the Merlins under the Excalibur prgramme
    The first one is built and looks just as good as the photo and fits into my bath

    • Articles like this one are spoilt by immediately telling that it is an Aprils Fool joke. The idea that you need a disclaimer at the end of an article like this s just cowardice on the part of the author. It was a good AF joke until the end though.

  2. Initially I thought. Yes. Yes, yes.
    Then rapidly realised…oh yeah it’s the 1st of April and besides HMG are never going to rearm and invest in our military properly.

  3. Oh and DIP is published today as the government agrees to up defence spending to 3% of GDP by next year in light of the threat from Russia and America

  4. Come on guys, you would have to possess an unhealthy amount of faith in this government if you believed even the title of this article
    Happy April fools 😜

  5. In news from Australia today the ADF has announced their latest low cost UAV. Based on an advanced wingless aerodynamic design and constructed from radar absorbing non ferrous organic derived material. It is designed to be man portable and can be hand launched by a soldier in the field with minimal training. Its advanced line of sight guidance system provides a return to home feature if it fails to find its target making it a cost effective solution for the war fighter.

    • Hi OZ, read somewhere that Germany is looking at the Ghost Bat. Wonder if NZ might adopt it. Its kind of jet fighterish.

      • If they like our new flying wooden wing (although TBH the design has been around for a while) I’ve got a bridge they might be interested in buying. 😉

  6. In fact it is so unobservable that we have ten sailing right now, guess where they all are! You guessed it right, Whitehall.

  7. April fools aside, AI should mean we could all make our fantasy fleet ships like that even down to virtual internal walk arounds inside the compartments .
    Would that make traditional naval design redundant along with the staff?

  8. I must have missed this when reading the Defence Investment this morning and they don’t cost anything either. This must be the “big bad Royal Navy” Hegseth referred to. Definitely trump’s any of the Donald’s toys.

  9. Love the “Avril Fuller” sign on….regards from 🇦🇺 where being upside down is the right way up!

  10. Hey Avril Fuller, like the double Samson radar for good redundancy there and forward gun looks enormous, maybe a navalised RCH 155mm to shoot at anything while on the move.

  11. This could work.

    I presume the super stealth mode should be quite cheap, all it needs is for someone to hide the relevant columns on the treasury excel sheet.

    Thats the main enemy defeated at very little cost.

  12. Excellent News . Lord Nelson can relax again knowing the Govt has seen sense and restored the Royal Navy to a correct capacity to protect the nations sea lanes for food enrrgy and trade in the interest of National security.

  13. Great news for the RN and the bean counters!!Perhaps the ultimate example of FFBNW..(Ships,not kit)!Good article UKDJ

  14. If you are going to do an April fools joke then try not to be quite so transparent, the idea of our government actually ordering anything other than more hotels for asylum seekers is fanciful

  15. What a waste of everyone’s time. Stop it… You are not in anyway funny and at this time, when the government is failing to defend the country it’s sick.

    Get some actual journalism done or leave

  16. The mere fact that a story about Britain actually ordering some warships is so obviously an April Fool is quite disturbing.

  17. So stealthy that we already have more than enough ships, the public just cant see them.
    Batch 2 of this class will be ordered once the manufacturer pays us to take them off their hands, with all funds to be spent on upgrading the rubber dingies used by people smugglers, with the spend justified by redesignating them as part of the coastguard and the RNLI.
