It' not vulnerable at all. In fact it is what they call a high value asset in termns of resources and protection allocated towards these aircraft.
There is nothing standard about the P8. The P8 has about $200 million worth of electronics and countermeasures installed on the airframe all doing various tasks.

The aircraft is designed to work in support of the Naval Fleet. One of the P8s purposes is to protect the fleet from Attack Submarines. Another purpose is to detect and destroy attack and Ballistic missile Submarines and to utilize the Fleet to assist with the ASW. As such, the P8 gets its Air Defence from the Fleet. Now, wherever our Naval Fleet is, there is also substantial Air Superiority capability. In other words, either the RAAF are flying their Super Hornets, or our fleet is operating under USN or USAF Air Cover. It depends where they are. If they are in the Mediterranean, then chances are that its USN providing the Air Cover as the P8 is probably assigned to the USN Fleet.
In addition, the P8's will not be operating in Littoral Seas most of the time. They will be in Blue Water. In the Middle of the pacific, Indian, Atlantic, and Arctic Circles doing what they are suppose to be doing. Therefore, out of range of most enemy Fighter Aircraft without refuelling capability.
They look at all these things before sending an aircraft out.
There are many more examples of high value assets such as the Wedgetail.
https://www.airforce.gov.au/Technology/ ... 1Q4caywtsoThese aircraft are highly protected. The chances of an enemy aircraft getting to one of these is minimal. The enemy will need to get through so many layers of protection before it gets to a Wedgetail or P8.
Andother highly protected asset is BBJ or the Prime Minister's jet.
https://www.airforce.gov.au/Technology/ ... r2t6wx4AV3This aircraft also has defensive capabilities similar to those found on the Wedgetails and P8s Plus, it will be under heavy escort if at war.
The P8, as well as the Wedgies and BBJ, have 6 Early Warning Devices for inbound missiles, have the ability of jamming and destroying the missiles enroute with their countermeasures. That is the last line of defence and it will only get to that if you get through all the other layers such as naval Point Area Defence, Air Su[eriority Aircraft which will suicide to protect these assets by placing themselves between the protected aircraft and the missile if they need to, and then all the Electronic Counter Measures.
https://www.airforce.gov.au/Technology/ ... r2t6wx4AV3You wouldn't even be able to talk on a CB in such an electronic warfare environment, let alone get an aircraft or missile close to a P8.
If the Russians can, well good luck to them. But geez, i don't think so.
