    A question I have: Does the SMART-L radar also provide fire control for the SSMs and naval gun, or is a separate radar required for that?

    SSM Targeting is possible with SMART-L, Tracking for Oto Melara (German F124 Sachsen-Class) not.
    For a gun-engagement you need an APAR FC-channel or a tracking with optical sensor MSP500.

    Cheers

    De-contamination….. (as practised by USN)….

    Sure, it can be used also for de-contamination, but normally it is used as contamination prevention. So you switch on this “pre-wetting” before you have to pass e.g. a fallout area

    Is this Alexander Nevski?
    The stern of the sail looks different to Yuri Dolgoruki, I think.

    Edit: Sorry for my lack of knowledge. After checking google, it doesn’t look like a borei-class at all.
    What projekt is it?

    Wondering,
    why russians still rely on fixed pitch propellers.
    Diesel engines in combination with variable pitch propellers are far more flexible in my opinion.

    Little known fact (courtesy of Twower) is that Transas of Russia has something like a 45% world market share in the maritime ECDIS business and they equip a lot of US Coast Guard ships and the ENTIRE German Navy with maps and navigation systems. This is an area where Russia actually leads the way.

    Transas also won a huge order to modernize the bridges of hundreds of Japanese merchantmen like a year ago. Transas is one of the few legit Russian high-tech success stories since the Cold War ended. Russia may not build too many merchantmen today, but their nav systems can be found on the bridges of half the new ones built today.

    Transas has also rather famously branched off into avionics too with their KBO family of avionic suites. And of course, they are trying to make a go of it in the UAV business as well with the Dozor family — basically the only decent models in Russia today.

    Hi,
    not wanting to spoil this thread, but I have to correct you in one point.

    True, TRANSAS ECDIS was retrofitted on most of the german ships, which came original with paper charts.
    Newer ships like F124 and K130 were installed with Raytheon ECDIS instead from the beginning. I also expect, that F125 will.
    Personally, I like the look and feal of Raytheon more.

    Cheers

    All that being said, how come a passive array like spy-1d has multiple emitters? They wrote each array has 8 of them. What do those emitters do? What is their purpose? Are they involved with providing midcourse updates?

    I have to confess I’m not to deep into SPY-1, but every phased array radar (also PESA) has multiple emitters. In case of PESA they are only driven by on single central wave generator and don’t generate the wave itself like AESA.
    So I could imagine that SPY has propably more than one wave generator to group different emitters of the array for different tasks.

    Hello,
    although this method is not that acurate, ESSM and SM-2 are able to be guided with S-band uplinks only and without X-band terminal illumination. I think its called quiet-mode.

    For F124 and LCF not APAR is the limiting factor. Its the processing power of the missile interface cabinet (MIC) between combat direction system (CDS) and Mk41 VLS.

    Cheers
