Acest tip de armament este conceput pentru a lovi tinte situate la distante mari in mai putin de o ora si ar putea inlocui rachetele balistice actuale. Unii suspecteaza Statele Unite ca ar vrea sa faca din acestea arme nucleare.
Zborul-test al rachetei de tip X-15A Waverider a durat aproximativ 200 de secunde. Este vorba despre cea mai lunga durata realizata pentru un dispozitiv de acest tip. Precedentul record, de 12 secunde, a fost realizat de racheta de tip X-43 a NASA, potrivit Mediafax
Dupa aproximativ 200 de secunde, o „anomalie a survenit, iar zborul s-a incheiat”, au precizat fortele armate aeriene, adaugand ca inginerii sai lucreaza pentru identificarea cauzelor problemei. Racheta a atins altitudinea de aproximativ 21.300 de metri.
