If Iran exploded a satellite with nuke in it, would our F-35's survive to defend a crippled America?

Yes, it's Photon Torpedoes and Death Rays aren't affected by EMP.

"B.12.3 EMP Protection
Electronic equipment can be EMP-hardened. The primary objective of EMP hardening is to reduce the electrical pulse entering a system or piece of equipment to a level that will not cause component burnout or operational upset. It is always cheaper and more effective to design the EMP protection into the system during design development. Potential hardening techniques include using certain materials as radio frequency shielding filters, using internal enclosed protective “cages” around essential electronic components, using enhanced electrical grounding, shielded cables, keeping the equipment in closed protective cases, or keeping the equipment in an EMP-protected room or facility. Normally, the hardening that permits equipment to operate in intense radar fields (e.g., helicopters that operate in front of a ship’s radars) also provides a significant degree of EMP protection."

since one of the Raptor's upgrade/enhancement is EMP protection i belive it's a serius threat and probably even F-35 will take it in consideration (if not yet).

I wonder how many Helicopter pilots and crews have had children after being in front of the same radars?

EMP protection is not for the circuits, it also has to encompass the wiring between the black boxes and, the power supply. EMP turns transistors (or any P-N junction) into a three way short circuit.
To me the real question is the F-35 EMP hardened more than any past fighters?

Yes, the F-35 and all military aircraft are designed and tested to survive nuclear EMP. There is a test site at NAS Patuxent River, MD which can simulate pulses up to 50kVm, and is used by all three military services. More info here: http://www.navair.navy.mil/nawcad/index ... A04BB0296D

Other types of electrical interference are also tested (known as E3 or 'E cubed'). Aircraft are literally winched of the ground in electrically shielded, anechoic chambers and have all systems tested for interoperability, against lightning strikes, enemy emissions, etc. http://www.navair.navy.mil/nawcad/index ...

Additional information
https://www.govinfo.gov/content/pkg/CHR ... g71526.pdf
At this week’s 2011 International Symposium on Electromagnetic Compatibility in Long Beach, CA, Fred Heather of the US Navy in Patuxent River, Maryland, gave an overview on the proposed addition of electrostatic discharge (ESD) and lightning testing to MIL-STD-461. Heather is the Electromagnetic Environmental Effects (E3) Lead for the U.S. government’s F-35 Joint Strike Fighter Program.

Currently, MIL-STD-461 is at revision F, so the new standard version will be MIL-STD-461G.

The changes propose to add four additional tests:

CS106
CS117
RS107
RS108
These tests are primarily based on the requirements from RTCA/DO 160 sections 22 and 23.

These changes are largely being driven by the use of composite materials in airframe construction, including that used in the Boeing 787 Dreamliner and Airbus A380. Many composites don’t conduct lightning currents the way metal airframes do, leading to the possibility of higher voltages and currents affecting aircraft equipment.

The changes were proposed for revision F, except the Navy and Air Force reportedly couldn’t agree on pin injection testing, thus delaying its implementation

Some more:
DTRA and its predecessor agencies have developed, and regularly update, military standards (MIL-STDs) designed to aid in the design, development, test, and evaluation of DoD systems subjected to nuclear and EMP environments. These MIL-STDs cover nuclear-generated EMP survivability of aircraft, maritime, and other systems in coordination with the Air Force and the Navy, as well as the broader community of stakeholders. The following are some of the relevant MIL-STDs:

MIL-STD-1766, Nuclear Hardness and Survivability Program Requirements for ICBM Weapon Systemsdefines nuclear hardness and survivability requirements and practices for use during the concept exploration, demonstration and validation, full-scale development, production, and deployment phases of the acquisition life-cycle of ICBM weapon systems.
MIL-STD-2169C, HEMP Environment Standard (Classified) defines high-altitude EMP environments for system hardness design and testing.

MIL-STD-3023, HEMP Protection for Military Aircraftestablishes design margin, performance metrics, and test protocols for HEMP protection of military aircraft with nuclear EMP survivability at three hardness levels. This MIL-STD may also be used for aircraft that support multiple missions. Subsystems of the aircraft required to fully comply with the provisions of the standard are designated as Mission-Critical Subsystems having a HEMP survivability requirement. This approach also allows for consideration of platforms not yet addressed in this standard, such as Unmanned Aerial Vehicles.

MIL-STD-188-125, HEMP Protection for Ground-Based C4I Facilities Performing Critical, Time Urgent Missionsis in the process of being updated. DTRA is investigating present capabilities and shortfalls of power filters as well as utilizing test results from EMP simulators.

MIL-STD-4023, Maritime EMP Standardestablishes performance metrics, test protocols, and hardness margin levels for HEMP protection of military surface ships that must function when subjected to a HEMP environment.

Satellite System Nuclear Survivability (SSNS) Environment Standard defines nuclear weapon environment levels for evaluating satellite system performance in nuclear scenarios.
Comprehensive Atmospheric Nuclear Environments Standard (CANES)provides detailed nuclear environments and effects for a number of different nuclear weapon-types as a function of height of burst. A supplement to this MIL-STD covers nuclear-disturbed communication environments and nuclear ground burst environments

It is a matter of helping the next person happen to have the same question, he may stubble upon this thread.

F-35s will be hardened against EMP. they are built to deploy nukes afterall.

People who ask these types of questions don't do research to begin with though, else they would have already stumbled upon the answer.
