Fixed fortifications in post ww2 period

During the period after ww1 lots of countries used fixed fortications and they persisted even after The advantages of mobile armored warfare became apparent such as the Maginot line Molotov and Stalin line , Gustav line etc

can we see a return to use of such elaborate fixed fortifications in the post ww2 era ?
what will they look like and how will they be different from the interwar and ww2 era ones ?
What measures can be taken to make them more resistant to postwar weapons ( inc NBC protection)

thanks
 
Actually happened OTL. Several elements of the Maginot line are still in use by the French air force to this day. The Italian Alpine Wall was in use until the 90s. The Swiss National Redoubt is still in use to this day
 
The Bar-Lev Line? Israeli and Syrian fortifications in and around the Golan Heights? Taiwanese coastal defense forts?
 
Were these fortifications expected to stop mechanized formations ?
Saddam did something similar in the iran iraq war esp using water obstacles
 
Add to the list of today's fixed fortifications: ICBM silos and the Ground-based Midcourse Missile Defense System at Ft. Greely
 
There are permanently emplaced, fixed air defense sites all over the world. They were especially common in the 1960s and 1970s when strategic air defenses could be reasonably oriented against enemy bombers and unitary RVs in the days before MRCs, MIRVs, and MARVs.
 
add to that the extensive frøy fortifications constructed post wwII in northern norway. They were finished in 1994.

Fixed fortifications can and will work even today, If left empty or armed with computer controlled weaponry they force an enemy to use guided weapons and or enter a SAM trap to engage. The prevalence of counter mortar and missile weapons can provide a level of defence.

Specifically no. Some were used for extend the life expectancy of assets that were not easily made mobile. ie: The ammunition storage sites of the Maginot line. The higher level CP sites of the Maginot fortresses were nuke resistant, buried deep underground as it were.
 
What about fortifications in situations outside of all out war?

We had an entire chain of watchtowers along the border and super sangers were a feature of a number of NI towns. Police stations and army barracks, especially in Republican areas, were essentially fortifications used to dominate territory in the exact way that the castles across North Wales were used seven or eight hundred years earlier.

Soviet SA2 and SA5 sites do they qualify as well ?
 
Am I right in thinking that the Soviets had a range of fixed defences on the Chinese border, albeit buried obsolete JSIII and T10 turrets/tanks - were they buried tanks or just the turrets?
