Sorry Shen, I do know what I am talking about.
If you look back at the initial attempts by the us with the typhoon an/spg-59 system of the 50s then the an/sps-33 and 34 systems of the 60s for the Enterprise and Long Beach and the issues those systems had and why...and then carefully look at how RCA learned from those problems starting in 1969 when developing an/spy-1 to initial deployment and test of the first engineering development model that was deployed on the uss norton sound in 1973, you will see that what I said is precisely true.
They used the what the did in that system because the state of the art technology at that time, based on the development chain I just cited, in terms of solid state, power, micronization, etc...paired with the design requirements...dictated that s-band had to be used.
They would not have used c-band in that time frame...and in fact we know that they did not. That was not because it was impossible, I never said that. It was because, given the technology and deign constraints, it was not something to consider. They all factor together.
You can argue until you are blue in the face, but those are the facts about how RCA came up with spy-1...and s-band that they used with it.
And they have continued to improve it ever since to the spy-1a first installed in 1983, to -1b in 1986, to -1d in 1991, -1d(v) in 1998, and so forth.
Next, the us navy will put the AMDR on the Buke IIIs which will be AESA and have both S and X-bands. The Ford class carriers will have the an/spy-3 and an/spy-4 DBR X and S-band radar. Exciting times.
But we are getting well off-topic. We've all had our say.
Back on topic to Japanese military news.
