We had a debate on whether to use PPP or the exchange rate previously in the Future PLAN Orbat Thread below from 2 years ago. Additional reading on the rationale for PPP below as well.
Note the producer price index (for manufacturing output) should be understated by the PPP exchange rate.
In other words, PPP overestimates the cost of Chinese equipment and supplies. The Chinese military actually gets them even cheaper.
Future Orbat Thread
I'll make it a new post, the Zumwalts and LCSs are - up projects, but Burke x Type 052D should be 'fair' as currently they're 'mainstays' of either navy

Before I start answering, how can you catch old arguments about something, because I try to search for a word and I always end up not finding it. This would make my life a lot easier, I've already tried to view it in the forum feedback, but I couldn't find it. If you can help me, I appreciate it.
My comment was oriented to the civil economy to explain that there are problems in measuring PPP GDP, but in practical terms, it is still the best measure to assess the potential and development of a national economy, the PPP GDP per capita is still the best measure to explain the development of an economy.
For example, in a basket of products that is used to compose the PPP GDP, it may be that such country - say Saudi Arabia - does not have the same consumption ratio and weight with another country, say France, in this PPP GDP conversion , there will be measurement problems because products that have been placed in a basket for comparison can be applied to one country, but it may not be applied to another country. Precisely for this reason, the sources that make this measurement such as the IMF, World Bank and others, there are always divergences and changes in the PPP GDP of each country, the list is never diametrically equal and this is related to the basket of products that is used to carry out the comparison.
In the military sphere, the PPP GDP definitely becomes the best measure to determine the level of spending on defense, but a country that imports many weapons will have to undergo corrections, because its imports are carried out at the market exchange price. India, for example, is a country that imports many weapons annually, just in military contracts signed with Russia, USA and France are more than US$80 billion, a country that carries out this level of import will suffer corrections in defense spending and the measure in PPP will become deficient. In the case of Chinese and Russian it is totally different.
For example, I know you like to put gun prices and I also share that premise, I read a while ago that a ton of common steel for ships in the US must cost somewhere around US$2,000, in China some time ago I read that cost somewhere around ¥5000 to ¥7000, that would be somewhere around $771 to $1,080. Obviously the price of steel by far is not even what most influences the price of the ship, but just as all production in China is nationalized, the same applies to Chinese combat systems, a while ago I saw that the radar of the Type 055 cost ¥1 billion, that's somewhere around US$154 million, Arleigh Burke III's SPY-6 radar costs over US$300 million.
Let's look at a middle ground that could apply to Indians, the KDX-III Batch II destroyer is a ship that is produced in South Korea, but the combat system is western (AN/SPY-1D(V), Aegis, SM -2 Block IIIB , SM-6 among others), in November it was published that the second ship in this class was contracted for production and the cost is US$538.9 million, this value is the price of the ship without the combat system. , based on the first ship built in its class (+US$930 million), this means that the combat systems that the South Korean destroyer will have are estimated to be in excess of US$400 million.
A case like the one above could not even be measured by the PPP method and these are the cases of countries that import at market price level like all European countries that import from the US, such as the Japanese case, South Korean, Australia between others. Strictly speaking, the nationalization index of China and Russia believes that the PPP measurement method is the most efficient for analyzing defense spending.
