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.

Northrop Grumman takes prime role for MK 54 MOD 2 lightweight torpedo - Naval News

Northrop Grumman has been contracted by the US Navy to integrate and perform initial proof of manufacture for the service's next-generation MK 54 MOD 2 lightweight torpedo

Launched from surface ships, fixed-wing aircraft, and helicopters, the MK54 MOD 2 Advanced Lightweight Torpedo is key to the U.S. Navy’s strategy to address modern and future submarine threats.

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.

Singapore to acquire Gulfstream G550 maritime patrol aircraft

Singapore will acquire an undisclosed number of Gulfstream G550 Maritime Surveillance Aircraft to enhance maritime domain awareness and complement its planned fleet of four Boeing P-8A Poseidon jets, the Ministry of Defence has announced.

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.

Behind an unusual two-for-one replacement of the Singapore Armed Forces’ Fokker 50s lies a secret edge capability, says author and former defence journalist David Boey.

I would have thought they would go straight to a high (manned P-8) and low (unmanned UAV) mix instead ......
