Boeing P-8A Poseidon (737-800EFV) MMA (Multi-mission Maritime Aircraft)

Denmark to purchase the P-8? That will be good news for them, but one question why only three aircraft? Though I suppose that Denmark will purchase more under a future deal.
 
That was what I was wondering about TomcatVIP with the purchase of the P-8 and with Greenland being owned by Denmark as well, they have an active airbase on Greenland too.

Cost.

It's going to take a long time before Europe groks just how much money they need to spend on defense.
 
RTX/Raytheon rec'd USN Dec. $86 million contract to upgrade the X-band APY-10 radar a development of the AN/APS-137 originally developed by TI for the S-3B ,which understand was the first radar to reliably track submarine periscopes at sea, APY-10 fitted in the nosecone of the P-8 Poseidon, what rather surprised me was the claimed 250 nm range against ships for a X-band radar.

It depends on the pulse repetition rate also. 250nm might just be the limit imposed by the rate.

IIRC it is a mechanical radar that spins at some kind of wild speed, to the point its radome enclosure is actually a sphere in vacuum. This apparently was more capable than even AESA for periscope detection, which is the primary mode.

Thought the P-8A Poseidon was optimized for ASW so had assumed APY-10 used a high PRF to give better speed measurement allowing for more precise tracking of moving targets - tracking of subs and periscopes in high sea clutter conditions though with drawback of range ambiguities, but as the P8A also tasked with anti-surface warfare e.g. LRASM and ISR so expect you are right radar using a low PRF for long range so it would appear to be the Navy choice for the APY-10 - Medium PRF is often a common pick for radars as it offers a compromise between range and velocity ambiguities.

Sounds right. A higher repetition rate is more limiting on range IIRC, because if the next pulse is transmitted before the reflection from the current one comes back, it creates ambiguity as to what range the target is at.

I'm not sure, but this model looks like it might be a -700 fuselage rather than the -800 fuselage that the P-8 actually uses. Could this just be a repurposed E-7 model that they modified and painted for the event? The E-7 strakes are significantly larger than the strakes on a P-8 with the AAS, which I suspect is because the shorter fuselage means the tail provides less directional stability.

Not P-8 related, but Singapore related :

Wonder what makes Singapore get so many MPAs in such a short time frame?

It's part of a general effort to extend their maritime reach, replacing a total of nine older Fokker-50 prop MPA with seven newer jets. It sounds like the Gulfstreams will be surface surveillance aircraft with large radars and likely some significant SIGINT capability.
 
British and Norwegian Boeing P-8 Poseidon maritime patrol aircraft have supported a UK-led operation to monitor three Russian submarines operating near underwater infrastructure in the UK’s exclusive economic zone.

Healey said that the Defense Ministry would boost the UK P-8 fleet with £100 million ($134 million) of extra cash, which defense sources say is funding an extension for support to the Scotland-based fleet.

First P-8 Poseidon Ever Built Starts New Career Supporting Pacific Missile Tests​

https://www.twz.com/air/first-p-8-p...s-new-career-supporting-pacific-missile-tests
The very first P-8A Poseidon aircraft is now assigned to Air Test and Evaluation Squadron 30 (VX-30), the “Bloodhounds.” TWZ was first to report last year that VX-30 was in line to get two P-8As to support long-range missile and other testing efforts. The aircraft will help the squadron address the increasing difficulties it is facing with its aging P-3 Orion aircraft. Only a handful of P-3s remain in service anywhere in the Navy, and are becoming increasingly challenging to operate and maintain.

Vil man købe en MPA, ja så er det jo Poseidon som er den bedste løsning, desværre er det amerikansk

This is how militaries alienate their own citizenry ... :rolleyes:
