Ja, det stemmer. Husker imidlertid fra lanseringen av Poseidon at de poengterte dette med at winglets gjorde maskinen ustabil i lav høyde.

One of the features on the P-8 that hints at its future service in antisubmarine work is its wingtips. Unlike the popular performance-enhancing winglets found on many commercial and business aircraft today, the wingtips on the Poseidon are a continuation of the wing, raked backward to better shed ice, given the adverse weather and altitudes the aircraft will be expected to patrol.
According to Boeing, the wingtips–not offered to commercial customers because of the additional length they add to the wingspan–give about the same level of performance as the winglet-equipped airplane.
