Sono leggermente più rumorosi al decollo, ma voleranno meno degli loro predecessori. È questa l’equazione con cui il Dipartimento federale della difesa (DDPS) ha spiegato come l’entrata in servizio dei caccia F-35A non aumenterà l’inquinamento fonico nei pressi degli aerodromi militari.
Il DDPS ha informato giovedì le autorità dei Comuni interessati. Il rumore a Payerne (VD) aumenterà di poco, a Emmen (LU) rimarrà sostanzialmente invariato mentre a Meiringen (BE) diminuirà leggermente. Un fattore decisivo, hanno spiegato i funzionari federali, è la significativa riduzione del numero di movimenti aerei.
L’Ufficio federale dell’armamento armasuisse ha calcolato le immissioni sonore con il Laboratorio federale di prova dei materiali e di ricerca (Empa) e con il supporto del costruttore Lockheed Martin.
L’entrata in servizio dei nuovi caccia F-35A è prevista per il 2028. La Svizzera ne ha acquistati 36 dagli USA per sostituire i suoi venticinque F-5 Tiger e i trenta F/A-18 Hornet.
