I'm not very sure about HVP on 155 mm. Yeah it is far cheaper than your daily MRSAM but the fire rate is going to be very, very low. To perform the engagement that a single SAM launcher performs, you would need a whole pack of howitzers. Think of it like using a single shot sniper with big reserve and a semi auto one with smaller reserve in an FPS game.

Naval guns are a different story though. They can fire more rapidly than 155 mm howitzers. Hell, this even makes me reconsider multi-barrel naval guns as you can fire salvos.

HİSAR-O SAMs Replace MIM-23 Hawks in Libya | TURDEF

ASELSAN's more modern HİSAR-O100 systems have replaced Al Watiya Airbase's MIM-23 Hawk medium-range air defence systems.

turdef.com

Turkiye has replaced the old school Hawk SAM systems stationed at Al-Wattiya base in Libya , with Hisar-O 100 AD systems. With dual-pulse motors and much improved seeker heads the Hisar-O missiles bring 21st century technology to the protection of the air base.

This is being regurgitated for the last few days, but original claim is from last year. We had argued whether a transfer was indeed made or not, which was later refuted. Turns out it was true.

I don't know what's going on is this Sanayi ve Savunma reliable source ? Anadolu Agency is a reliable source. Meanwhile, Gabya class frigates are anchored in the port.

You are correct. Firing speed is slower. But then again Firtina-1 has a firing mode of 3 shells in 15 seconds with different elevations that allows it to hit same target at the same time. In reality it can fire 3 rounds in 15 seconds. However, the more you fire in succession the quicker you destroy your barrel. US army has asked their technical team to overcome the destructive effect of the quick successive firing and increase the speed of reloads.
127mm naval gun can shoot 32rounds per minute. So that could be the target speed I guess!
But on the up side; an AD battery has in its canisters 6-8 missiles. A howitzer can have 48 to 60 rounds ready to fire successively. Reload of expended shells, also, is faster.
You can also make up for the speed deficiency by using 2 howitzers in tandem.

Simply because naval cannons have no restriction of space of height and can utilize all means of automatic reloading, cooling. But USN has discarded 155 mm project for naval cannons, as well.

Naval cannons have a barrel cooling, and wide space for installation/foundation/dampers. It eases the entire operation, flushing the barrel, cooling non-stop.

USN has discarded 155 mm AGS entirely for CPS missiles, well, sucks for them to miss the opportunity.

Speaking of wear and stuff, I'm sure a hyper-velocity bullet to hit hypersonic speeds is prone to put more heat (metaphorically) on the barrel compared to a conventional round.

To be honest, we should consider DART-like ammunition or ATOM for 127 mm (TF-2000 and Barbaros) and 76 mm naval guns.

...Because they made the ammo for that gun incompatible with regular 155 mm Howitzers.

Then they refused to buy the bloody ammo because it was "too expensive"

There are lessons to be learned here for us.

AGS used a 62 caliber gun to achieve that muzzle velocity and range as LRLAP weighs more than double of a standard 155mm shell. At the time, M109 howitzer used a 39 cal gun. T155 uses a 52 cal gun. There was no possibility to use LRLAP on standard 155mm guns. Cost ballooned because US cancelled most of the Zumwalt class, not because ammo itself was directly expensive.

"The AGS uses the same 155 mm caliber as most American field artillery forces, although it is unable to fire the same ammunition due to differences in the size and shape of both projectile and firing charges."

Its not a caliber thing.

Gun's length is caliber. That's why other 155mm guns in US army service can't fire LRLAP as pointed out by @Sanchez .

You are correct from heat damage point of view.
But there is also the raw physical damage due to high kinetic energy that is imparted by the round to the barrel lining which effects the wear negatively, as the round leaves the barrel at extreme speeds.
No cooling will have any effect on this type of physical wear. Also higher pressure of propellant will induce wear irrespective of cooling process.

It is important that the rifled lining of the barrel is in good condition. As the round is pushed out by the exploding propellant, it is vital that no gasses are leaking and escaping ahead of the round and decreasing muzzle velocity.
The HVP rounds that BAE Systems have developed are designed such that they are very aerodynamic and consist of a surface that help propel them out of the barrel at very high speeds. Nevertheless due to the high exit speeds, the abrasive forces acting on the barrel lining are so intense that New technologies regarding materials must be developed to increase the lining life.

If we manage multistatik radar,there will be at least 3 radar one is for active and others are passive,the question is active radar wil have only transmitter modules not reciever ones that gives more room for T modules which gives more power,so this add more capability to detect VLO aircrafts like F35.

Not particularly that but also in earlier times Zumwalt was meant to be that stealth ship conducting shore and territorial bombardment which required those dual 155 mm. And yeah, we are in 21st century now and USN almost shifted whole surface strike capability to the submarine force.

I wish we could do the same, even the thought alone feels good.

Do you mean ASuW capabilities? Otherwise each DDG and carrier strike wing still carry substantial land attack capabilities, no?

And here's the Gökdemir(Turkish Nasams) test footage at last.

Shame on TUSAŞ,we still use bunshee target drone.

They're old, so it makes sense to get rid of them first.
TUSAS is making wonders and some of you are shaming it. Unbelievable!

Firstly, this is an old video. We know Gökdemir test was made at least a year ago from the accompanied photo which was made public in 2023 at the latest. Adding, That's a Banshee 80 twin engine target drone. It's not old, it's a perfect target drone, cheap and is basically an industry standard at this point. And it perfectly matches the threats Gökdoğan will be used against. It can fly up to mach 0.6 and 30k feet. And I don't think Süper Şimşek is ready.
