The US, UK and other P-8A Poseidon operators have ordered a system to verify forces as friendly and determine their bearing and range.

Telephonics Corp has been awarded a $15,130,351 contract for the procurement of a maximum quantity of 50 Identification Friend or Foe Interrogator (IFFI) AN/UPX-43(V) 1 and 50 IFFI mounting trays, repair of repairables and required technical data in support of P-8A Poseidon Production Lots 9, 10, and 11 for the US Navy, partner countries and foreign military sales customers.

The AN/UPX-43, say its manufacturers, is a ‘monopulse and AIMS certified IFF interrogator designed for command and control’.

It enables air traffic controllers and air defenders to identify military and civilian aircraft, verify forces as friendly and determine their bearing and range. The AN/UPX-43 also provides multi-channel Automatic Dependent Surveillance-Broadcast (ADS-B) and has been deployed in airborne, shipboard and ground-based environments. The system complies with all US and international specifications that define interrogator modes, performance, control, reporting and interface say the company.

“To easily introduce performance upgrades, the system uses common module hardware and software for the detection, interrogation, identification, tracking and data extraction of small targets in severe environments.”

According to a contract notice, work will be performed in Farmingdale, New York, and is expected to be completed in November 2021.

“Fiscal 2018 aircraft procurement (Navy); and FMS funds in the amount of $3,588,904 will be obligated at time of award; none of which will expire at the end of the current fiscal year. The first order combines purchases for the Navy ($2,687,946; 75 percent); and the government of the United Kingdom ($900,958; 25 percent).

This contract was not competitively procured pursuant to 10 U.S. Code 2304(c)(1). The Naval Air Warfare Center Aircraft Division, Lakehurst, New Jersey, is the contracting activity (N68335-19-D-0002).”

Systems like this are found on almost all types of military aircraft.

I wonder where some countries will feature after Brexit!


Maybe it will have a “Frenemies” setting for them!


You do what do you mean “after” BREXIT ?


“Church orders pews”

Being a bit of a Simpleton but Being able to read recent events and Articles, I would suggest that Any Aircraft of European ( Especially Belgium, Spain, Germany and to some degree France), Russian, Chinese, Argentinian and North Korean Origin, would be seen as Foe at the moment. Just an opinion.


I assume this is some next level sarcasm that is just lost on me.

I hope because we are only getting 9 we do get all the capabilitys this great plane has to offer.

Glenn Ridsdale

They’ll be identical to the current USN standard. Any changes would add to the cost.

Cam Hunter

Yeah but the British version will have added over land surveillance capability, when the RAF sentinel R1 fleet go out of service the Poseidon will take over their duties!! I hope we get a new R1 fleet and I’m sure 9 isn’t enough for marine and overland!, maybe the reason a government adviser comity has suggested a further 7 poseidons are needed for the duties we will need it to carry out. But we should have a dedicated over land like we currently do! Not a specialised marine with added land capability!! Money saving no doubt!

David Flandry

Well then they need to order 4 more.

Anyone know why hose and drogue, such as that retrofitted to RAF airframes in the past, eg. MR2, E3, C130 and even Vulcan etc., cannot be fitted to the Poseidon to keep it tactically in line with other platforms. Even the F35B has managed it…?
