HMS Glasgow, currently undergoing fitting out at the BAE Systems facility in Scotstoun on the River Clyde, appears to have started the process of having her main gun fitted.

Earlier in the year, we reported that HMS Glasgow had reached approximately 65% completion, marking significant advancements in its construction phase.

The focus had been on major equipment installations, including the fitting of the bow sonar and preparations for the main gun installation.

The gun is the 5-inch (127mm) Mk 45 Mod 4 Naval Gun system already in service with the U.S. Navy. Here’s how the gun will look.

The Mk 45 naval gun system, as described by its developers, BAE Systems, is promoted as ā€œthe worldā€™s lightest and most compact 5-inch, 54-calibre fully automatic naval gun system.ā€ Initially deployed on the U.S. Navy’s CALIFORNIA and VIRGINIA-Class cruisers, as well as SPRUANCE-Class destroyers, this system has reportedly been installed on over 200 ships, including those of allied nations. BAE Systems highlights that the early versions, Mods 0 through 2, were designed with continuous technological enhancements aimed at improving system controls and ammunition handling, which they claim resulted in better reliability and maintainability.

The latest iteration, the Mk 45 Mod 4, is described by BAE Systems as a significant upgrade, featuring a longer 62-calibre barrel intended to enhance the gun’s range and accuracy, particularly for Naval Surface Fire Support (NSFS) missions. The company asserts that the Mod 4 incorporates major subsystem upgrades to handle high-energy munitions and optimise the performance of various ammunition types. Additional design improvements are said to focus on ease of operation and maintenance, as well as reducing the radar signature of the gun mount, which BAE Systems suggests could enhance the system’s adaptability and efficiency in modern naval warfare.

According to BAE Systems, the Mk 45 Mod 4 is designed for flexibility and resilience, with the capability to handle a wide range of 5-inch ammunition types, including conventional and extended-length projectiles.

The system is claimed to offer high ammunition selectivity and loading flexibility, allowing for automatic operation that is responsive to changing mission needs.

BAE Systems also notes that the system is built to endure harsh environmental conditions, including extreme weather and missile blasts, while maintaining consistent performance, which they state contributes to the system’s high mission availability. They further claim that ā€œall-weather operation for the entire range of Mods 0 through 2 and 4 variantsā€ is assured by the watertight gun shield enclosures.

BAE Systems also emphasises the Mk 45 Mod 4’s operational versatility, particularly its ability to handle a diverse inventory of ammunition types, which the brochure describes as a key feature. The system is designed with ā€œremote round-to-round selectivity,ā€ allowing operators to select and fire different types of ammunition without manual intervention, which BAE Systems claims enhances the gun’s flexibility in rapidly changing combat situations.

The company highlights the systemā€™s compatibility with various fire control systems (FCS), stating that the Mk 45 can be adapted to the latest digital fire control interfaces. According to the brochure, this adaptability ensures that ā€œthe inherent gun pointing accuracy of Mk 45 Mod 4 maximises the overall gun weapon system accuracy achievable with any FCS,ā€ suggesting that the system is future-proofed for evolving technological standards and operational requirements.

The build process for each ship involves its structure being completed in Govan where skilled teams of fabricators and steelworkers construct the units before they are assembled into two main blocks which are joined together externally on the hardstanding before the ship departs.

In Scotstoun, the shipā€™s outfit is completed and the complex systems are installed before test and commissioning takes place. Currently in Scotstoun for outfitting, Glasgow is on the cusp of entering its testing and commissioning phases. With sea trials anticipated in 2026. As the first ship in class, HMS Glasgow is expected to enter service in 2028.

I would also add the potential for future longer ranged and guided ammo over the service life of the frigates.
BAE recently restarted, or so I gather, their Hypervelocity Projectile programme. This is supposedly a guided, extremely aerodynamic sabot shell that can be used for ballistic missile defence and also anti-surface.
No details on guidance method, possibly imaging or command guided, but anti-everything over 50 miles sounds nice to me.

It’s already been successfully trialled from the 5″ by the USN. It got quietly shelved by the USN, after they needed to save some cash. But since the Houthis attacks on shipping in and around the Red Sea this year. The Hypervelocity Projectile (HVP) is being looked at again, as another method to deal with both asymmetric and conventional threats, i.e suicide UAVs and USVs, along with cruise and ballistic missiles. One big factor is cost. The guided HVP is expected to cost less than $100k, whereas ESSM costs about $1.8M. Especially pertinent when in April the US Navy Secretary… Read more Ā»

Hi Sailorboy. I do have a few nuggets. The first is when fired from the 5ā€ the HVP reaches a terminal speed of just over Mach 3. When fired from a 155 Paladin it reaches Mach 4.5. But when fired from the M110 203mm howitzer, it is just above Mach 5. When fired from the rail gun it was reaching speeds up to Mach 7. Though it was predicted to reach Mach 9 in later tests. The 155 and 203 guns have much larger breech chamber volumes, than the 5ā€, so can use a lot more propellant, hence the higher… Read more Ā»

Whatever DO you do at work, DB? Thanks for the summary. I think you’ve told me most of that before (not the HVP stuff) but it’s nice to see the options laid out. Wasn’t MAD-FIRES grinding to a halt? Something about the seeker (SAR IIRC) not working well enough? DART seems the best of the options in terms of scalability and capability fired from the 5″, unless some sort of family could be developed for madfires that retains commonality of components for both 57mm and 5″.

Let’s put it like this, if the Government cancels one of the key forthcoming defence programs, I will be mightily pi**ed off! From reading between the lines from the DARPA and Raytheon’s blurb. I believe MAD-FIRES will be using semi-active radar homing (SARH), rather than command guidance, as it will be significantly more accurate. Which for a CIWS role is critical. A little known fact about Leonardo’s DART, is that BAe helped design the guidance system, which has in part been subsequently used in the HVP. The biggest advantage MAD-FIRES has over DART will be the higher number of targets… Read more Ā»

Putting 12.5% of your only of non repalceable surface ASW assets in range of enemy drones, SPGs or truck mounted ASM seems a risk.
If anything T31 should have the NGS role.
A 57mm on T26 could deal with fast boats out to 15km, and with the right ammo drones and air threats, as well as saving weight for additional VLS.

The drones going against fixed land-based targets have the intelligence of a PTI at a spelling test. They fly flat dumb and happy to a GPS location and then stop flying to hit it.

Fly a drone 1200km at 200Km per hour and when it arrives the ship it was aimed at will be anything up to 180 nm away or if you include course as well then anywhere in over 100,000 Km of sea area.

Indeed, I donā€™t think most people have quite considered the level of energy dumped into a hull, when a 100kg object hits it at around 2500mph, especially as that object will tumble, shatter and has a blast frag warhead to shatter itself and ensure every bit of energy is expended into the hull. Thatā€™s far more destructive weapon than say an 8inch shell..and a 10kg warhead is nothing to be sniffing at.

The gun – i hope RN is not that idiotic to curtail the capability like it did to 4.5″ – can also hit air drones.

The Type 26 should have around 400 rounds of 5″, should you use expensive and much more limited number of missiles in a 300kt air drones or 40kt sea drones?
The Type 45 was recently expending Asters into drone that had a little better than WW1 performance aircraft.

A couple of points: 1. Aster can pull a higher “G” turn than CAMM. This is due to the mid-body strakes, that create lift when turning. However, the knock on effect is that by generating that lift, it looses energy more quickly. 2. CAMM is a lot more aerodynamic than Aster, as it only has the tail fins. CAMM can reach a comparable terminal velocity to Aster 15 (Mach 3) without the additional 1st stage booster, but it doesn’t loose speed as quickly after the motor has burnt out. 3. The “Piff-Paff” reaction jets are mounted mid-body. This is designed… Read more Ā»

If you are worried about it then Salvo shoot. The KP miss chance then is so small as to be negligible.

Fair question. I can’t judge. My understanding is that the experts consider things from a holistic weapon system perspective i.e. effectiveness = radar + software +cms+ decoys+ missile + guns. So destroying the incoming is good, but forcing it wide is also a result. Aster is very good, otherwise the RN would not have chosen it. Interesting that the Italians developed Camm- ER; I assume this will enable engagement of higher altitude missiles at greater range and give you more shots; Aster level probability of a kill without requiring top end radars like Samson?

Having 127mm gun in T26 is nothing bad. Putting the 127mm on T31 and let T26 with 57mm is also no bad. It is not “which is the only choice”. 1: If a CVSG is made of 1 CV, 1 SSS, 1 Tide, 2 T45 and 2 T26 (with 127mm), that is the “max” RN can provide. ALL active T31 will be needed to cover other tasks, like KIPION and FRE. Sending T26 “near” shore is a risk, but it is now 40-100km from the shore, not 5-10 km like it was on 1980s.

I’d rather hope T45 to be equipped with a 57mm gun and two 40mm guns (like T31), as they will not be expensive. As this will save a lot of weight, I even hope to add “24 more” (total 48) CAMMs using the weight.

These guns will also be essential drone defense tools, albeit for short range. I understand some escorts will be surrounding the CVF, and T45 will be located relatively near so she can do the close-in defense there (coupled with another T45 (or T31) in the other side).

Surely the primary role of that gun is to support ground forces. It can’t be to enage enemy ships, surely?

What anti-ship missiles capable of 20 mile range might the enemy gound forces have on-shore?

Using Ukraine as the recent example. Ukraine’s Army/Militia were using ATGMs against Russian landing craft and patrol boats. I don’t think they used them against the Russian corvettes, as they didn’t come close enough.

Why not? What is different about doing NGS now as opposed to 50+ years ago. Nothing. Missiles where a thing 50+ years ago. They where a thing in the Falklands. They where a thing off Iraq They where a thing off Libya. Fast boats and fast surface targets are easily killed by NGS. You don’t need to hit, you just need to get close… ish. Set to VT High or VT Low and the shell will airburst and spread the love around over a 100+m radius. Looking at a shell burst on a THIM lets you see how far all… Read more Ā»

Canada interestingly choose the competitor, the Leonardo Oto Melara 127/64.
Maybe because they already had the 70’s Oto Melara earlier variant in their Iroquois destroyers.

76mm on the HK boats.
Some went to the Irish and have paid off.
The last 3 went to the Philippines and I think are still in service.
I was the Level 3 Base maintainer 1993-1996 for the Oto .

Interestingly the RN removed the AA predictor capability from the Sea Archer FCS
It was deemed that having that capability may have annoyed the futureoccupants of Stonecutters Island and POW Barracks.

Would it be possible to quad pack spear 3 into the mk41 or even a deck launcher? It would give these ships a great weapon for small craft and shore bombardment from 80 miles.

If you could figure a way to stack them you could probably fit 16 in there! Tiny little things, you fit eight in an F-35B.
Probably more likely to hang then off your helicopter.

Would need a booster to get them up to speed, though.
That dinky little jet engine isn’t going to get them out of the VLS fast enough.
The same goes for helicopters, the lower launch speed impacts range.
The best option would be for the Navy to try to get the Army Land Precision Strike launched from VLS like CAMM.
Brimstone accuracy and supersonic out to 80km.

Yep, absolutely and it’s mk41s so you can hot launch it.
As for ALPS, there is something to be said for maintaining your native science, engineering and manufacturing capability rather than buy a foreign weapon.
UK had learnt that lesson rather painfully and repeatedly.
And there’s something to be said for the capability to launch a 16 missile salvo from a single Mk41s tube! šŸ˜‚

Land Precision Strike is an MBDA UK thing, so sovereign capability is there.
I think you are confusing it with the Precision Strike Missile (PrSM) which is US.
An air launched PrSM would be fun, but not really feasible (more like Kinzhal).
LPS is based on Spear but is longer to fit a bigger warhead and more fuel to maintain range, as well has having the rocket booster. I think you would quad pack in mk41 but vertical stacking doesn’t sound like a good idea.

It’s just a comparison to the Soviet tecknowlogy in the cold war top hat bass tilts drum kits are all nato code names for the Soviet main gun systems on thier ships.top hat means target housing. Drum kit and bass tilt have to do with Soviet fire control and target acquisition of thier ships “main gun”.Sorry if I seemed a little to inundated.

Not useless but some would get through.
That’s why it isn’t the only gun on there and there are 4 others that can also take down drones, not to mention CAMM.

I like your confidence in unproven defensive weapons systems .I seem to remember watching a documentary on the Falklands campaign which highlighted how ineffective our warships were in defending themselves against low flying aircraft dropping simple bombs. I canā€™t see it being any different decades later if we had a similar scenario ,defending against modern missile attack systems, or drone swarms.

They couldn’t defend against aircraft because our self defence SAMs at the time, that we relied upon completely, were terrible.
Now we have Sea Ceptor, the 30mm and working Phalanx, this is one of the most well protected ships we’ve ever had against a drone swarm.
The use of the 5″ for air defence is at best a secondary function.
