Indirect Fires Modernization Project - C3/M777 Replacement

PrairieFella said:
If the Koreans are putting these on the table for us, we'd be insane to say no. That's double the range of the M109A7 with Excalibur.

The barrel to achieve that range already existed in the XM1299 ERCA. That project was cancelled for a number of reasons including excessive barrel wear and other technical challenges.

Once you start pushing rounds out at ever increasing speeds with ever increasing chamber pressures, you hit a point where current metallurgy can't hack it. With the XM1299, the science looked good but the practical firing test showed the weaknesses.

I'll believe Hanwha's glossy brochures after the K9A3 has gone through a couple of months at Yuma testing grounds.

Even if realistically they hit 75% of what they claim, that still outranges peer equipment by 50%. That's some serious overmatch.

While testing data will actually tell the real story, wouldn't excess wear from those long ranges only be a concern when shooting at those ranges? If If the barrel wear issue remains the same as with the XM1299, then wouldn't reserving that capability for emergencies and just firing on lower charge levels solve that issue? Plus keeping some additional spare barrels for when that emergency occurs.

South Korea’s Hanwha and Poland’s WB Group agree to guided missile joint venture in Poland - Breaking Defense

“In 2024, we signed a second agreement for 72 Homar-K [Chunmoo] systems […]. This is the first stage of transferring the production technology of Chunmoo launchers to Poland,” Secretary of State at Poland’s Ministry of National Defense Paweł Bejda said at the ceremony.

290 launchers ordered with 90 delivered and mounted on locally manufactured Polish trucks. 60 of the 290 units to be manufactured complete in Poland. Poland will also be manufacturing its own missiles and selling them to other European countries.

Are we European?

Poland is also developing a Medium Range CAMM missile with the UK for land and sea applications.

MBDA, Poland’s PGZ to develop medium-range air defense missile

The ambition is for the new missile to serve both the Polish and British militaries as a common munition with a dual source of production.

Serious ally. Poland is definitely moving up to the ranks of a UK/France in terms of capability. Dare I say that they have the opportunity to push Germany out of the way of number 4 within the current NATO makeup?

My guess is that, in the not too distant future, UAV 'A-10' type support will be the norm...

Poland has committed to building the largest Army in Europe.
They already outstrip the Germany, UK and France as far as Army forces - the question will be what they do with their Air Force.

They are so lock step with the SK's maybe they are in the middle of negotiations to build within the Poland the KF-21.

The bigger issue is nuclear forces.

Poland seeks access to nuclear arms and looks to build half-million-man army

Already a major spender within NATO, Warsaw has massive military plans as fears grow about the reliability of the U.S. as an ally against Russia.

If they start building Ritz Carleton hotels across the country that's the sign that they're taking the Air Force seriously.

French simpler systems are doing great in Ukraine. Something that maybe we need to think about.

Well, we could always ask for a K9A3 (with the automation benefits...assuming they can be tested and confirmed to be reliable) with the L52 barrel.
 
is there a reason the specific barrel lengths are chosen? And not some other length
L39
L52
L58
For tanks
L44
L52 Leclerc
L55
